I find it a shame that these days many channels use video titles that aren't at all descriptive of what the video is about. I typically don't bother clicking. This video's topic is especially interesting and I'm lucky I clicked on it.
Yes, I know it's for the algorithm. I usually make it a point not to click videos like this. My actions are only a drop in the bucket, but if everyone followed suit we could change the algorithm/tactic. Regarding the comment about Jay - I agree, he's become worse and I stopped watching his videos. I try and support creators that don't bow to poor tactics such as Gamers Nexus and L1.
I remember having my harddrive die on me when I was maybe like 15. It was like 3 am and I was working on some of my music when it happened and I thought I lost everything and just started crying. I had years of writing, pictures and so much more on that drive and when it failed it made my heart break. Luckily the data was salvageable but ever since that incident I have been super careful with backups and cloud storage on all of my devices. Never wanna go through something like that again.
I'm glad at the very least that all my pictures and most of my important data has been backed up to the cloud and locally is on SSDs now. I still have a single, used, 500GB HDD in my machine that is more just for random videos I've made or other not really needed files.
@D never read better words in my life lol. Aussie internet is 100000% worse than almost any country out there. Even the average school network connection per user is like 2mbps, in the US that would be at least 20. Australians have it harder than alot of people when it comes to internet.
I just now discovered that one of my 1TB HDDs has been in the process of failing for 2 months after seeing several critical errors in Event Viewer, I am now in the process of migrating my data to another drive. I avoided an absolute catastrophe thanks to this video. Absolute W
Many years ago I had two 80gig hard drives in raid 0 for OS, apps, and a lot of personal files. One of them started squeaking, but I ignored it. Then one day it made a sound like a shovel being dragged across concrete and died. Nothing was recoverable, and I learned some valuable lessons.
A good tip to hearing a drive even in a case with fans going. is a non-magnetic screwdriver. rest the tip of the driver (bigger the better) on the drive surface gently and put the handle in your ear... the sound travels up the driver and you can hear it. even in a server with multiple drives. Do not impale yourself!
My best tale for data recovery comes from my early teens. I was 1. Dumb, 2. Not financially stable, and 3. DUMB. I was able to totally recover all of my data from an old 60GB drive with a combination of a week of time, a freezer, and lots of attempts with ddrescue. I was ultimately able to get a bit-accurate image, and restored it to another junky drive from a recycling pull... That promptly died as well. And what was I trying to save? Some old game repacks that took a long time to download over dialup. Just had to save that copy of UT2K4. The good ol' days.
For its age, the original hard drive in my oldest laptop still works fine with no bad sectors. Its a Toshiba Satellite 330 CDS from 1998 with its original 4 gb hard drive. Not bad that it still works fine even after almost 24 years since it was made and I have it running Windows 98 second edition.
@@FreakyCh3rry it means an area of a hard disk platter that is damaged physically, either by contaminants getting into the drive of the head scratching the platter due to the hard disk being handled too rough.
Out of literally thousands of drive failures I have seen over the years, I have only ever seen S.M.A.R.T detect a problem on 2 drives that I didn't already know were failing. I have also had drives that S.M.A.R.T condemned very early on in life last for 5-6 additional years without any issue so I don't really trust S.M.A.R.T data for anything other than a quick gauge to see what the drive has been through and potential physical issues it may already be suffering from.
i have some drive tester with that on my desktop ive had since april 2021, the hdd is still at "100% health" while the ssd has decreased to 96% in 17 months, i have no idea how its possible
@@Rhyean2004 Drive SSD health is based on how many writes you have done. If you're writing, erasing, etc.. is going to reduce it quickly. On the good side compared to HDDS.. HDDS can die instantly with no way to recover from one day to another (clicking problem). While SSDs usually degrade until they are do not allow you to write anymore, but your data can be still recovered.
You must be much better than the average techie at identifying issues then. I also have had SMART detect two failing drives (that later would fail), but in my case I've only had 4 of my drives fail in my life, and the first two were before I knew anything about computers. (a couple weeks old Samsung 1.5TB and an aging Maxtor 120GB) As for drives it detected that would later die, I only remember the story of one of them. I picked up two Seagate 500GB drives I saw laying on the concrete next to a dumpster. Both of them had reallocated sectors but were virtually unused. One of them got worse quickly and ended up dying, the other kept working until I no longer needed it. I think they were old spares from a company that they literally tossed out (looked clean & near-pristine)
Last year, bought a brand new HDD from Best Buy. Put it into my NAS and ran an extended SMART test before doing anything else... 1000s of bad sectors right off the bat. Return and replaced, and new one is still working great today.
The hour+ long extended SMART test is great to run on any drive of unknown condition, new or used. It's like running a few hours of Memtest86(+) on new RAM before you trust it.
Usually what I do with new drives is run a single pass wipe and then an extended SMART test. The wipe ensures that all sectors have been written to and SMART may have something to actually read. You still need to monitor the drive for about a month, but it does help a fair amount.
Actually had a drive issue very recently. Turned out my harddrive was getting oddly warm and caused it to crash everytime i was gaming off of it. Cleaned my pc, upgraded cooling, no more crashing, no event viewer logs
Getting too hot can cause long-term damage to a harddrive as well (I've killed a couple like this), so I'd recommend making sure everything is backed up right now, and replace the drive when you can.
I am a former data recovery engineer and data recovery can be both difficult and expensive. Worst single hard recovery required a new pcb, firmware repair (took me a month to find matching firmware to get modules), 5 separate head exchanges and had heavily degraded surface. Even more so are the number of drives that suffered platter damage… platter damage isn’t recoverable folks. Your data is scrapped from the surface and becomes dust in the filter. So many people I have worked with in computer repair think their computer or external being slow is because it is old… or they just keep data on an external with no backup.
We have a dead external hard drive where the controller messed up the data. I've told my dad to create an image from the drive and then use recovery software. Do you have a recommendation for a software to try? The drive itself is readable, but a Linux system is not finding interpretable data on the partitions.
As someone who's been in computer repair and sent drives out for recovery quotes, how recoverable are head crashing drives? I always quoted customers the cleanroom recovery for those.
@@jonnyspeed8974 head comes into contact with the platter and physically removed your data by ripping the surface up. Scraping it off the surface. Instead of a shiny disk it has lines in it or worse looks heavy abraded.
I've always found it odd that none of the drives I've used have ever failed. I still use an external drive my dad bought like almost 15 years ago for himself and it still works and only had 3 bad sectors last time I checked.
All my IDE drives from the 1980s and 1990s eventually croaked by the end of the 2000s. My 2000s drives all died, too. But everything I've had since the 2010s has been surviving. My oldest working drives now began use in 2012. In my machine I use most, I've got two drives from 2018 that seem to be working... although, since June, the 2018 mechanical has been making a clockbeat rhythm and I'm unsure why. I'll load it up in BIOS soon and see if it's doing it there, too. I can easily sustain the loss, and it's a smaller capacity single terrabyte drive. If it's making the sounds in BIOS after I reseat the drives in the drive bay, and all the cables, then I suppose that's fine. I was intending to replace the drive anyway in the near future. I think you're right, Aki. My experience with modern junk is that it's great, at least compared to the old IDE drives. LOL Those things are dinosaur tech.
I have a drive from 2006 that still appears to be working as of less than a year ago. I haven't used it recently, but I wouldn't be surprised if it still works. I've been fortunate so far as well and have never seen a hard drive fail either. Believe it or not, I've had RAM fail on me before. Very weird odds of what I've seen if you ask me.
I had a laptop with 150gb hdd and windows installed on it, one day it. Suddenly became extremely slow, like it would take a few minutes to open file explorer. I was able to navigate through the lag, download a linux distribution and flash onto a USB. Disk checking in it indeed showed me that the hard drive was failing. Fortunately I could still access my files from the live USB and upload them to cloud.
@@tspooner01 Yes and no. The newer systems have fans that don't spin all the time or will spin slowly. This is also a sign that the fans are failing. I did have one fail though and I was able to tell because that particular fan never came on even when the others were screaming along at the highest RPM. Poking the fan with a small plastic stirrer resulted in the fan spinning up, which means the motor or bearings are failing. If the fan makes noise though, that's a bit different.
SSD failure is usually gradual unless the controller just gives up in one go, where you can't tell that will happen outside of knowing that the product line is faulty. Otherwise things like flash exhaustion the SSD will report, and Windows will notify the user that there is an issue (Windows checks SMART stats).
@@Clavichordist easy enough, install speed fan or adjust the fan curve in the bios, see if it spins up. If you need to check the actual rpm, tachometers are like $30, though don't think you'll get a case where it won't be whining if fan bearing is coming loose, so checking the actual RPM doesn't really make sense.
I've had pretty good luck with high capacity refurbished enterprise drives for my home NAS. As long as you buy from a reputable vendor (read: not ebay) they'll have some sort of warranty and easy(ish) return policy.
Nothing wrong with eBay, just have to double check it comes with a warranty from the company and it's a reputable seller and not 60 year old Jim from IT selling random drives out his closet.
@@thiefrules I like Server Supply for used drives, but if you are wanting to roll the dice, Amazon and Newegg Marketplace often have used drives for sale. Just make sure you get some kind of warranty, erase the entire drive as step one (to protect yourself), and then run a full smart diagnostic (to check or bad sectors), follow by benchmarks (to make sure the drive isn't crap performance like a dying drive often is). Return any drive with bad, reallocated, or unstable sectors.
I used to work for a PC warranty place (early-to-mid 2000s) and in our engineers handbook we literally had 'lift the PC 2 inches off the ground and drop' as the official solution to resolve a stuck hard drive (when the head keeps clicking rather than reading/parking). I remember thinking it was a bit odd but when one of my hard drives got stuck I did it and it worked (took two drops though). Of course I ordered a new hard drive and transferred the data because I knew I'd have caused some surface damage to the platters but I couldn't have got my data (without one of those super expensive data recovery companies) without that maneuverer and would have lost everything. Sometimes mechanical issues require mechanical solutions, not saying it works every time but it's def worth a go before spending money on a data recovery service.
My mother worked in IT and this was a legit solution at her work. (It was the easier version of opening the computer taking the hard drive out and slinging it, which was the earlier fix.)
@@foodhatesme You're calling a hard drives paper weights? And no it's not caused by a stepper motor, stuck heads are caused by numerous things such as dirt/lube build up, shock damage, failed pre-amps.
The usual first sign of a magnetic drive on its way out due to substrate failure is when Windows throws a delayed write failed error. You might also get loads of errors in the SMART error log. That's the point where you should already have made backups, and if not, get the most critical shit copied off ASAP because the drive isn't likely to survive the day. I've had several hard drives go out this way, and the fun part is that the failures are predictable months in advance if you do sequential read tests of the whole drive and you have sections where the read speed drops through the floor, as those are areas where the substrate is already failing, but hasn't quite gone completely dead yet.

Thanks big dog, mi NAS se jodieron dos discos así con 8Tb. Dammm
After experiencing an almost a hard drive failure myself, i learn quite a lot from pushing it beyond the limits. I pushed it so hard the reallocated sectors count froze on 9 800 and hasn't changed since.
@@msh6610 that's the big I don't like about SDD's, they just don't seem safe place for you data, If when I do get one, have a back up copy of SDD's on a regular spinning rust in size alone, a too three time the size to the price of SDD's
@Telleva why do parents should buy you new one? Get a job and buy it yourself, and don't say that a kid can't get job until he has degree in first place why does a 12 yr old kid needs multiple hdd? This is not your parents duty to buy.
My laptop's hard drive was a tank, it survived ten years in backpacks, luggage, being thrown around in checked luggage by airport staff, me shaking the laptop, being dropped tens of times while running, from heights spanning from 1ft to the top of a 6ft ladder (the display broke lol). I only replaced it because after all that, it only could push 20MB/s read and it was _slightly_ painful to wait that long for everything
Hey, just wanted to say thanks for this video. I am old enough that I should definitely know better. Your vid prompted me to check my only remaining HDD status. Got 'Pred Fail' and found loads of bad block errors. Replaced with a 1TB SDD. Thank you Anthony!
I went to the store and bought a 4tb NAS. Suprisingly the NAS itself was cheaper then the drive on amazon. I pulled the drive from it and have been using it for about 2 years with no issues whatsoever.
Fun video, Having experienced plenty of hardware failures on all kinds of storage due to work and my own personal storage at home, I'm probably never beyond 200 feet of a failing or failed hard drive. I say this because the video came up and I was just looking at a box with 5 untested hard drives. Certainly helped pass the time while I check them before backing up anything salvageable off them.
I have had more than my fair share of hard drives go bye bye....but they do usually give you plenty of warning before going boom. Anthony does his usual great job of explaining this of course, and we are all saved now!
@@getridofit3 Not just the seagate 3TB drives though, they were the worst but in general the whole 3 TB generation seemed cursed, I kinda skipped it and am still at (mostly seagate) 2TB and 4 TB drives atm and those have been rock solid for me. some of the 2 TB ones are over 10 yrs old now I think and still doing fine.
I've never gotten over my first ever HDD dying around 2010. Back then as a kid I had absolutely no idea about backups and safety. The only files I was able to recover were some that I burned onto DVD's or put them on USB sticks. But there's still a lot of data from these times I wish I still had. Back then my family used to just dump photos from our digital camera's SD card onto the PC and then just wipe the card to have space for new photos. Most of these are gone. So yeah, protect your data! Right now I have a NAS built from an old PC and some used HDD's there but once I have enough funds I'm planning to buy new NAS grade drives and run them alongside the original pool with a copy of the data.
My 2TB hard drive I bought from Newegg came in a big cardboard box with NO padding whatsoever. I’m wondering if I should’ve returned it now… It could done a barrel roll in the box if it was thrown hard enough, and nothing would’ve stopped it.
S.M.A.R.T. tracking is the only tracking i support with no questions. It can tell you how many hours the drive has been powered on and each time it has been turned to park or stopped as well as what Anthony mentioned.
You can also initiate SMART self-tests with smartmontools that are both OS-independent and log the results to the drive's internal SMART self-test log. Whenever I get a new magnetic drive, first thing I do is a selective test across the whole surface (smartctl -t select,0-max) so that if a new drive arrives with any bad sectors, it goes straight back to the vendor for replacement, and the drive is basically blighted at that point because the self-test results are baked into the drive's self-test log.
I recently ordered a 4tb Exos drive that was advertised as brand new, after opening it, i immediately knew that it was pre-owned so I fired up CrystalDiskInfo and lo and behold, it had been powered on for 36000 hours and only powered on 24 times. Thankfully, the seller was willing to give a refund so it all worked out. Thank god for SMART.
@@dirg3music I've had some drives where the CrystalDiskInfo stats just don't make sense. Such as those numbers you describe. What situation would a drive only be booted some two dozen times for over 30k hours?
@@FlyboyHelosim Servers. I have a few dozen drives running that have over 55'000h of run time, and where only powered on 3-4 times. (mind you, Seagate Exos drives are enterprise drives)
@@RobinCernyMitSuffix Yeah, sure. Except I don't have any server hard drives. The scenario I talked about applies to consumer-grade hard drives taken out of laptops. I've also noticed erroneous numbers linked to hard drives taken out of things like Sky TV boxes.
Victoria HDD/SSD is the tool of choice for me. It's free and has a lot more information and indications of a bad drive. You can even find out if the sectors are weak (but not dead yet).
I got two decommissioned servers, each with 4/8 bays filled with 1TB drives, and obviously the pc hardware, raid cards and PSUs. Worth way more than the fifty bucks I paid. I have the drives in RAID with one redundant drive, and important data is backed up daily to my NAS (also used drives). The NAS data is backed up onto the RAID array. So if either one fails, I can simply buy a proper 8TB drive new and restore from backup, without much fuss. Yes, used drives are a gamble, but it's not too bad if you're smart about it.
So I know they say NOT to open a drive in a standard room because there's dust and particles in the air that can destroy it, but what about opening a drive outside? Since there's no dust outside would it make sense to open a hard drive on a table or something outside in an open field?
Outdoor air is absolutely full of pollutants. The amount of dust, pollen and god knows what else is in outdoor air in a field has to be astronomical. Clean room standards are incredibly exacting,. So no, you can't open a drive and expect to get it back if you do it in a field. In fact, if you open a drive at all even in a clean room you need pros to get the data off the platters.
My WD Green 4tb drive is a remnant from the first PC I built in 2014, and it's still working without errors as my main data drive for Windows. I've always left my PCs constantly running, with the option to turn off the hard drives during inactivity disabled, and it seems to be working for me so far. Yeah though, even though the SMART data is all fine (except for Load/Unload Cycle Count and Power on Hours), I'm planning to replace it sometime this year. I would've already done that if my data wasn't already backed up on an external HDD.
I have a routine for HDD. Brand new or used when received : check the smart and do a complete surface test with HDtune or HDSentinel to see if there are any errors If errors are found : return to amazon If ok : enjoy but always monitor and remember avoiding drop, vibrations and use a UPS
my amazon drives always go into my unraid server, and always 3 passes of preclear. If the packaging was...questionable...then 4 or 5 passes. I think i've actually only had to return 1 drive so far.
Hard Disk Sentinel says that my drive is nearly dead. It's at 9% Health. So many problems. And yet, when I decided to go and see files that are stored on those "dead sectors", the files are there and that sector still works. The 'wmic" test, says the drive is "OK"... So I don't know anymore...
"...vibrations..." Im surprised my 10 year old Xbox 360's hard drive hasn't died yet considering a lot of disc based games cause the whole console to vibrate A LOT.
What a coincidence! I was already running a SMART test of my hard drives 15 minutes before I saw this video ---btw DriveDX is a very good software option for Mac users
Thank you by telling me about crystal disc info you helped me save half of my data from failing with that device but it’s safe now because I’m trans ported it to my other healthy disc thanks so much
Had a few failures over my years. Most were insignificant. Only one was slightly significant as it was a failure of one of my servers HDD's. Thanks to the combo of zfs and zed I got an email about the failure while I was sitting in school (this is several years back now) so I was able to just pick up a replacement drive on my walk back home and swap it in.
Hah, back in high school (almost 20 years ago...) my dad's work laptop died due to a seized drive... opened that sucker up in the cleanest area of the house, poked the spindle, sealed it back up, and used that drive and laptop as a server for four years. I only retired it because I wanted a more powerful machine. Sometimes these machines can surprise you.
You got lucky. Next time use a laminar flow hood. Any dust can murder a drive and there are millions if not billions of dust particles in a clean home.
Drives sometimes do operations that aren't transperant to the viewer that could be mistaken as failure. I believe some have to do with getting rid of stiction for instance.
Compared to original IDE drives (the old school 20, 40, and 80 mb ones - if you were rich)...today's drives seem to be a much more dependable option. Not sure if their MTBF data show any actual projected increase in lifespan, but anecdotally? Yeah. they're better for sure.

Ohmygod I needed this. My PC is always notifying me to "scan for drive errors" every start up. I'm also experiencing stuttering whenever I play videos that are on the hard drive but not one's on the ssd. I'm going to check out the softwares mentioned here. Thanks LTT!
Another thing is, just touch it on occasion, or check the temps if it has that. Drives can get warm and sometimes, near death, they get damned hot even if they aren't making much noise. Had one from work where the motor was failing, but was failing in such a way it was generating a ton of heat, but not vibrating weirdly, though it was also reading and writing ridiculously slowly.
SMART is (in my experience) totally unreliable. Disks die without ever giving an early warning through SMART. I just don't think hard drive vendors want to tell the customer that the disk is failing because they don't want warranty repairs, so it is not in their interest to signal early failure... Just treat disks as unreliable things and have a backup. No point in trying to predict anything here, really.
I just wish there was a solid program that could actually interpret the individual SMART values without needing background in what they each mean. Past CrystalDiskInfo's "Good/Caution/Fail" that is.
20+ years ago I had my hd kick the bucket... while tripping on 'shrooms. All was great with the world, pc crashed, hd was screaming inside the case, and it turned into my WORST trip EVER. So bad that I've never took hallucinogens after that. So I guess good things can happen when your hd crashes.
Hard Disk Sentinel is a program that I use. Once you start using it will start recording the "health" in percentage (estimate of life left) for SSD and HDD as well as let you see S.M.A.R.T and gives a estimated lifetime writes
Booted up my Quantum Fireball 20Gb from 1999 a few days ago. Still works like a charm, no harsh noises either. Perhaps newer drives are more prone to fail.
I've bought 4 "New Pull" HDDs over the span of 6 years and only one of them has failed 6 months ago, but granted it was the older one I bought. I'd say it's pretty safe to buy these types of drives, I've had OEM HDDs -especially from HP PC's and laptops- fail much faster (and way harder) than these used ones. Obviously YMMV, but I'd still say these types of drives are a pretty good deal IMO.
New 22tb drives were released yesterday, can't wait to order 6 of them and give my server more storage. I've got drives that have 11 years worth of power on time and still going strong....and others that die after less than 2 years
Why new drives that haven’t been tested in the field yet? Certain batches/models of drives are more prone to failure, so i typically wait for backblaze to have a significant sample size first, which usually takes a few years. My next drives will probably be a few of the Toshiba 16tb.
As an IT guy, having experienced firsthand how unreliable spinning rust is, my instinct when someone asks me this question is to always reply with, 'yes, yes it probably is.' You can never trust hard drives, especially consumer level stuff (laptops/external drives etc).
yeah they just die and die and die. SSDs have proven soo much more reliable for me. 50% of the hard disks my family and I have used have died, yet only two SSDs have died so far. One being a 2011 OCZ SSD that became well-known for being unreliable, and the other the cheapest SSD I ever bought, which died in the first 2 weeks. I personally use my SSDs very heavily and like to run them in RAID0 (I know..)
@@n646n Same. Never experienced a hard drive failure within 20 years of using computers. Many second hand purchases. Cheap flash drives on the other hand
i actually have CrystalDiskInfo running in the background all the time and it notifies me if a problem has started with the HDD and fun fact: my (my old) Hearing aids have a t-coil mode that i can use to listen to the electrical signals coming off of the hard drive and i can tell if something is wrong with it...
Ahh. Nothing better than watching a relaxing LTT video only to be confronted by the horror that several of your drives are dying and you never would have known had it not been for this content.
What a coincidence that this video shows up couple days after I noticed that my oldest (7 years) SSD has been throwing up Event ID 7 (bad block) messages on Event Viewer for months. Weirdly it's failing sooner than my 11-year-old HDD. Hopefully you'll make that SSD version of this video soon 😅
Samsung SDD from early 2021? RMA it, these are known factory defects on models from January to April 2021. You will get a new one that doesn't age prematurely.
@@Grocel512 SSD in question is Samsung 850 Evo from 2015 so no RMA but I have to keep your comment in mind and check my Samsung 970s which I bought in 2021, they might be from that batch even though they still work perfectly.
@@Fortzon You should be fine then. The nvme products were not affected. If you had a SATA 870 EVO 2TB or 4TB you would have to watch out for ECC error rate and unrecoverable error rates. I had an affected unit (4TB) that I RMA'ed.
Last winter the NVME M.2 SSD on my laptop died for no reason, and it took a week to find a data recovery company and then 1.5 months to do recovery + 2 months to bring in order what has been recovered. After that day I always create backups on external drives, on a regular basis :)
The same can be said for SSDs. The moment it has begun its use, it is on the slow path to failure. NAND flash has a limited write cycle count that only gets worse as more layers are added, and there are many electronic components that can fail on an SSD as they can on an HDD. Recovering an HDD is more likely to be successful though as the only things a person needs are the platters and the small chip that stores info on the specifics of that drive. Everything else can be replaced. An SSD is a LOT more complicated (data is usually spread randomly between chips for wear leveling because of the write cycle issue, can be encrypted, the controller must match, firmware must be the same, etc.). Plain and simple, can't beat them for archival storage unless you go to magnetic tapes.
8:49 "trust me guys, hard drive failure sucks, unlike our sponsor: War Thunder..." as someone who still today storage a broken 2TB hard drive and plays War Thunder every day I can say that youre wrong. hard drive failure does sucks, but nothing sucks more than War Thunder.
According to a decade of extensive testing by Google across its millions of datacentre drives, SMART is not a reliable, or even unreliable, measure of the health of a hard drive. What boggles my mind is that the two of the three most reliable measures are completely ignored: sound and latency. Sound is mostly indicative of bearing wear, though it also speaks to behaviour which SMART should be reporting if it's problematic, ie uncorrectable error rate, which leads to... Higher latency is by far the most important metric. As a drive ages it has an increased media error rate, and that leads to it re-reading blocks and after a simple re-read fails - re-calibrating. It's the re-calibrating that is the most obvious audible behaviour change with an unhealthy drive. The latency is easy to ignore, but you do so at your peril. Lastly, spin-up duration is also indicative of both bearing health and media health. In a sane world the OS would be keeping stats for how long spin-up takes, and when a trend towards longer duration is established, the drive should be powered off and you should be warned to duplicate it in read-only mode before its imminent demise. SMART record, but not log, spin-up time. Out of context of past behaviour it's nearly meaningless.
SSDs have very limited write cycles, and it eventually dies when written to so many times. So while it theoretically have a long read-only life cycle, it’s not always the use-case.
Good ones are between 4 to 8 times more expensive for the same storage and have a limited number of write times that is significantly inferior to what an HDD can bring to the table.
Sure, and that's probably the recommended strategy for most uses just because of power consumption, which I'm very conscious of during this heatwave. That having been said, it gets expensive when your storage demands exceed about 4 terabytes.
Probably in a world of how it used to be, but I have long been a massive fan of Spinrite. Has recovered more than a few hardrives and data that was otherwise considered too bad to recover.
I was going to buy an external hdd at my go to pc shop, also got some ram and asked for regular 3.5 hdds, the guy just handed me free 500gb hdds, got 4 of them for free, now i have 2tb of free storage, and i use it for backup! They were used on old servers, but were from 2014-2015, i got there in 2019, so i thought what the hell, they are free, lets try them out, still safely saving my music and photos till this day, shout out *undisclosed* pc shop! Your services were simply the best!
One thing you also need to be aware of is that when you want to use Enterprise disks in a PC you need to make sure the "power on reset" doesn't get a signal (mostly with older power supplies). When this pin gets power the hard drive will not spin up. Easiest way to fix this is using a molex to sata adapter.
8:23 some games especially older ones don't save online, ME legendary edition has constant issues where the save doesn't carry over to the cloud and the local save is your most recent option. I back up all of my save data using Google drives auto backup feature for that
I helped a guy a few years ago his drive had the tick of death. I told him it was a long shot, but I put his drive in the freezer for a couple hours. I pulled it out, connected it to a USB adapter and it spun up. I copied all the data off that he cared about and saved the day. I've only had this work once.

Wish you'd added info to this video about the 'defect spare list' table used for bad block reallocation. It is typically 5% of the drive capacity and is one of the main reasons your 1TB drive comes out to ~947GB. Another part of that total loss is the mebibyte/megabyte issue, commonly referred to as 'marketing math'. Bad block reallocation is normal because *infrequent* bad blocks are normal. If they occur too fast, too frequently or if the defect spare list is full, the drive will go into SMART failure. SMART failure can occur for other reasons, but these are the most common. Firmware bugs can cause drive hangs and bad blocks (which can influence the SMART threshold tables), so keeping firmware updated when bugs are found is a good idea. Once a drive goes into SMART failure, there is no way to clear it (without manufacturer tools). Do firmware updates as preventative maintenance.
This video came at the right time to remind me to A.Finish cleaning up (and moving data off) the old HDD I have (I bought more SSD and now I don't need this old HDD anymore, especially since its probably more than 10 years old) and B.Once that's done, do a full backup.
Meanwhile a friends dad had a hard drive with increasingly bad sectors, a semi broken MBR and no backup. As soon as we found the issue we made a backup, but yet he still went on and did all of his work on that very drive for another two years. Until his outlook database got struck. The recovery program didn't want to recover the files and he didn't save the correct file. Luckily cloning the drive with ddrescue and repairing the database on the clone was possible and all of his work of the past 6 months was saved. The new hard drive hasn't shown any issues so far, but the file system is still the same, so we are now trying to get away from that machine and sort all the data accumulated over the last 10 years as soon as he has another system to work with. Hopefully with a better backup strategy
Six years ago, my 2tb drive wouldn't spin up. Stuck it in the freezer for an hour, and it's been working great ever since. My Hitachi drives are 11 years old and still going strong, they're the best in the business!
For more than a decade I have used a multi-tier mirroring backup strategy. So far I've never lost anything. Every computer in my home has a Data drive where the files are stored, I never use the OS drive for data, and that Data drive has a DataBackup Robocopy Mirror drive in the same case. Then every computer has TWO external hard drives that the Data drive is also Robocopy mirrored to. Then I have a NAS that has 32TB in it that every computer is also Robocopy mirrored to. And finally, I have a large Google Drive where my most important files are backed up to. I also have all of my code on a Microsoft Azure repository for an additional backup of my software development. Using Robocopy scripts means that I can quickly double click on a batch file to perform any of the required backups to any of the destination devices.
This is very relevant to my interests as I've got a bunch of old hard drives I recently put into a computer after years of sitting idle and I want to see if they are healthy.
1. Well, if you buy used drive only way to be really sure about the state is to run smartmontools (smartctl) and extensive test. This will rewrite whole disk multiple times with particular patterns to really uncover any hidden bad sectors. (it could take days to finish based on capacity so ideally run it from smth like Raspberry pi with disk in USB docking box) 2. It would be worth to mention - especially on LTT - that raw smart data which are shown in SMART reporting tools (like Crystal Disk info) are manufacture specific, many times it's hexadecimal so need to be converted. And even when converted to decimal there might be values like threshold is 100 and actual value 120 it does not mean it's wrong some manufactured are actually using values as lower limit. Or value is not continuous but discrete. You need to find details on each manufactured how to interpret values. 3. Do the backup ;)
Dying hard drive? More like “Dude, watching these videos makes me feel alive!” I simply love how LTT provides us with so much useful and fascinating information.
I would advise against thinking of cloud storage as any kind of backup, unless it's on a "cloud" you really, really, own personally, like on a physical server in a datacenter. The problem with storing your data in the cloud is that you do not own your data anymore, the company that provides the cloud storage does. Even if it was due to circumstances beyond your control or even if you yourself operated in good faith, the moment a piece of data is stored in "your" cloud that they deem as violating their terms of service, they will block access to your data and they will not feel obligated to restore your access under virtually any circumstance. This is not because they are "evil", but because they will get in a lot more trouble than you will if they do not follow through on fighting wat could be illegal content in their cloud environment. The good adage stating "better safe than sorry" may apply to individuals and we as individual citizens may follow that advice, but the big companies that provide cloud storage to us and to other companies have no choice in that whatsoever.
wtf illegal content are you storing on the cloud??? Sounds like you're the problem here, buddy. I might not trust cloud storage entirely either, but if you've got nothing to hide your argument is moot.
@@skilletborne You are missing the point. It is not about what is illegal or not, it is about not owning your own data and not using the cloud as a backup for it. A file on your cloud storage does not have to contain actual illegal content to be deemed in violation of the terms of service and the moment you start using cloud data storage, you accept the terms of service of the cloud provider. They can deny you access anytime if they deem it necessary or appropiate. In other words: you are no longer the true owner of your data. This has been brought to civil courts on multiple occasions. An innocent picture of one's child playing on the beach, an unopened document sent to a unwitting receiver, etc., etc., all backed up to the cloud.There was no wrongdoing of any kind by the person whose account was blocked (or worse: one's family account, in which case entire families are hit by this). And in those cases, even though the judge recognized the fact that there was no actual wrongdoing, they were (legally) unable to force the cloud providers to restore access, because of the violation of the terms of service, unwitting or not, did happen. Legal scholars have commented on this and stated that there should be legislation in place to deal with these cases and protect the rights of the consumer in these circumstances. In most countries in Europe at least, such legislation does not exist. Not yet. Also, the argument of not having anything to hide is a logical fallacy. Everyone has something to hide and everyone has a right to keep certain aspects of his life secret. Take, for instance, the PIN number to one's debit card.
Awesome video would be really cool to see more troubleshooting tips for commonish issues "is you're pc randomly crashing? Here is 10 ways to troubleshoot" I'll be expecting the SSD sequel shortly 👌
(This is early onset) If you are noticing any errors what so ever. there is another option... after your diagnostics have shown there is a drive failure. You can use "HDD regenerator" this can potentially move information on bad sectors to un-allocated sectors... once completed a windows health check is needed through command prompt outside windows "chkdsk /f /r" ... once completed the drive should be repaired to an extent(data wise).... use a clone program to clone the data from the bad drive to a new drive. Hope this helps
what's weird is that i've never seen a smart warning in my life but my brother has. multiple times. usually for me i'll break my drive (by dropping it or something) before it fails due to smart errors. no idea why drives go from good to warning in that case - just time? overusage?

I remember having my harddrive die on me when I was maybe like 15. It was like 3 am and I was working on some of my music when it happened and I thought I lost everything and just started crying. I had years of writing, pictures and so much more on that drive and when it failed it made my heart break. Luckily the data was salvageable but ever since that incident I have been super careful with backups and cloud storage on all of my devices. Never wanna go through something like that again.

I'm glad at the very least that all my pictures and most of my important data has been backed up to the cloud and locally is on SSDs now. I still have a single, used, 500GB HDD in my machine that is more just for random videos I've made or other not really needed files.

Many years ago I had two 80gig hard drives in raid 0 for OS, apps, and a lot of personal files. One of them started squeaking, but I ignored it. Then one day it made a sound like a shovel being dragged across concrete and died. Nothing was recoverable, and I learned some valuable lessons.
A good tip to hearing a drive even in a case with fans going. is a non-magnetic screwdriver. rest the tip of the driver (bigger the better) on the drive surface gently and put the handle in your ear... the sound travels up the driver and you can hear it. even in a server with multiple drives. Do not impale yourself!
Instructions unclear. Perforated my ear ball.
classic technique used by mechanics too. helps you zero in on clicking noises when an engine is making all sorts of racket everywhere else.
You should specify non-magnetic screwdriver.

My best tale for data recovery comes from my early teens. I was 1. Dumb, 2. Not financially stable, and 3. DUMB. I was able to totally recover all of my data from an old 60GB drive with a combination of a week of time, a freezer, and lots of attempts with ddrescue. I was ultimately able to get a bit-accurate image, and restored it to another junky drive from a recycling pull... That promptly died as well. And what was I trying to save? Some old game repacks that took a long time to download over dialup. Just had to save that copy of UT2K4. The good ol' days.
UT2k4 is worth saving brother. A good save.
I saved UT2K4 when formatting HDD even tho I had it on my disc. That game is worth saving on multiple backups.
Woah! DDRescue is older than I expected

For its age, the original hard drive in my oldest laptop still works fine with no bad sectors. Its a Toshiba Satellite 330 CDS from 1998 with its original 4 gb hard drive. Not bad that it still works fine even after almost 24 years since it was made and I have it running Windows 98 second edition.
Make sure to remove the backup batteries from under the keyboard. When they leak they can destroy the mainboard.
how much on-time? that is the main contributor to hard drive aging
What does bad sectors mean?
@@FreakyCh3rry it means an area of a hard disk platter that is damaged physically, either by contaminants getting into the drive of the head scratching the platter due to the hard disk being handled too rough.

Out of literally thousands of drive failures I have seen over the years, I have only ever seen S.M.A.R.T detect a problem on 2 drives that I didn't already know were failing. I have also had drives that S.M.A.R.T condemned very early on in life last for 5-6 additional years without any issue so I don't really trust S.M.A.R.T data for anything other than a quick gauge to see what the drive has been through and potential physical issues it may already be suffering from.

i have some drive tester with that on my desktop ive had since april 2021, the hdd is still at "100% health" while the ssd has decreased to 96% in 17 months, i have no idea how its possible
@@Rhyean2004 Drive SSD health is based on how many writes you have done.
If you're writing, erasing, etc.. is going to reduce it quickly.
On the good side compared to HDDS.. HDDS can die instantly with no way to recover from one day to another (clicking problem). While SSDs usually degrade until they are do not allow you to write anymore, but your data can be still recovered.
You must be much better than the average techie at identifying issues then. I also have had SMART detect two failing drives (that later would fail), but in my case I've only had 4 of my drives fail in my life, and the first two were before I knew anything about computers. (a couple weeks old Samsung 1.5TB and an aging Maxtor 120GB)
As for drives it detected that would later die, I only remember the story of one of them. I picked up two Seagate 500GB drives I saw laying on the concrete next to a dumpster. Both of them had reallocated sectors but were virtually unused. One of them got worse quickly and ended up dying, the other kept working until I no longer needed it. I think they were old spares from a company that they literally tossed out (looked clean & near-pristine)
Last year, bought a brand new HDD from Best Buy. Put it into my NAS and ran an extended SMART test before doing anything else... 1000s of bad sectors right off the bat. Return and replaced, and new one is still working great today.
The hour+ long extended SMART test is great to run on any drive of unknown condition, new or used. It's like running a few hours of Memtest86(+) on new RAM before you trust it.
Usually what I do with new drives is run a single pass wipe and then an extended SMART test. The wipe ensures that all sectors have been written to and SMART may have something to actually read. You still need to monitor the drive for about a month, but it does help a fair amount.
Actually had a drive issue very recently. Turned out my harddrive was getting oddly warm and caused it to crash everytime i was gaming off of it. Cleaned my pc, upgraded cooling, no more crashing, no event viewer logs
Getting too hot can cause long-term damage to a harddrive as well (I've killed a couple like this), so I'd recommend making sure everything is backed up right now, and replace the drive when you can.
I am a former data recovery engineer and data recovery can be both difficult and expensive. Worst single hard recovery required a new pcb, firmware repair (took me a month to find matching firmware to get modules), 5 separate head exchanges and had heavily degraded surface.
Even more so are the number of drives that suffered platter damage… platter damage isn’t recoverable folks. Your data is scrapped from the surface and becomes dust in the filter.
So many people I have worked with in computer repair think their computer or external being slow is because it is old… or they just keep data on an external with no backup.
do you mean scraped?
We have a dead external hard drive where the controller messed up the data. I've told my dad to create an image from the drive and then use recovery software. Do you have a recommendation for a software to try? The drive itself is readable, but a Linux system is not finding interpretable data on the partitions.
@@AlexanderEngler testdisk will search for partitions and optionally update the partition table.
As someone who's been in computer repair and sent drives out for recovery quotes, how recoverable are head crashing drives? I always quoted customers the cleanroom recovery for those.
@@jonnyspeed8974 head comes into contact with the platter and physically removed your data by ripping the surface up. Scraping it off the surface. Instead of a shiny disk it has lines in it or worse looks heavy abraded.
I've always found it odd that none of the drives I've used have ever failed. I still use an external drive my dad bought like almost 15 years ago for himself and it still works and only had 3 bad sectors last time I checked.
All my IDE drives from the 1980s and 1990s eventually croaked by the end of the 2000s. My 2000s drives all died, too. But everything I've had since the 2010s has been surviving. My oldest working drives now began use in 2012.
In my machine I use most, I've got two drives from 2018 that seem to be working... although, since June, the 2018 mechanical has been making a clockbeat rhythm and I'm unsure why. I'll load it up in BIOS soon and see if it's doing it there, too. I can easily sustain the loss, and it's a smaller capacity single terrabyte drive. If it's making the sounds in BIOS after I reseat the drives in the drive bay, and all the cables, then I suppose that's fine. I was intending to replace the drive anyway in the near future.
I think you're right, Aki. My experience with modern junk is that it's great, at least compared to the old IDE drives. LOL Those things are dinosaur tech.
I have a drive from 2006 that still appears to be working as of less than a year ago. I haven't used it recently, but I wouldn't be surprised if it still works. I've been fortunate so far as well and have never seen a hard drive fail either. Believe it or not, I've had RAM fail on me before. Very weird odds of what I've seen if you ask me.
I had a laptop with 150gb hdd and windows installed on it, one day it. Suddenly became extremely slow, like it would take a few minutes to open file explorer. I was able to navigate through the lag, download a linux distribution and flash onto a USB. Disk checking in it indeed showed me that the hard drive was failing. Fortunately I could still access my files from the live USB and upload them to cloud.
This is a great video! I hope LTT does more like this, signs of SSD failure, fan failure, etc...
That may be one of the lab functions
161 000 views in the first 2 hours is catastrophic for a channel this large, so they probably won't.
@@tspooner01 Yes and no. The newer systems have fans that don't spin all the time or will spin slowly. This is also a sign that the fans are failing. I did have one fail though and I was able to tell because that particular fan never came on even when the others were screaming along at the highest RPM. Poking the fan with a small plastic stirrer resulted in the fan spinning up, which means the motor or bearings are failing.
If the fan makes noise though, that's a bit different.
SSD failure is usually gradual unless the controller just gives up in one go, where you can't tell that will happen outside of knowing that the product line is faulty.
Otherwise things like flash exhaustion the SSD will report, and Windows will notify the user that there is an issue (Windows checks SMART stats).
@@Clavichordist easy enough, install speed fan or adjust the fan curve in the bios, see if it spins up. If you need to check the actual rpm, tachometers are like $30, though don't think you'll get a case where it won't be whining if fan bearing is coming loose, so checking the actual RPM doesn't really make sense.
I've had pretty good luck with high capacity refurbished enterprise drives for my home NAS. As long as you buy from a reputable vendor (read: not ebay) they'll have some sort of warranty and easy(ish) return policy.
what are some reputable vendors?
Please list some resellers 😁
Nothing wrong with eBay, just have to double check it comes with a warranty from the company and it's a reputable seller and not 60 year old Jim from IT selling random drives out his closet.
@@thiefrules I like Server Supply for used drives, but if you are wanting to roll the dice, Amazon and Newegg Marketplace often have used drives for sale. Just make sure you get some kind of warranty, erase the entire drive as step one (to protect yourself), and then run a full smart diagnostic (to check or bad sectors), follow by benchmarks (to make sure the drive isn't crap performance like a dying drive often is). Return any drive with bad, reallocated, or unstable sectors.
@@thiefrules all my refurbished drives came with fresh 3-5 years warranty from Western Digital... ..
I used to work for a PC warranty place (early-to-mid 2000s) and in our engineers handbook we literally had 'lift the PC 2 inches off the ground and drop' as the official solution to resolve a stuck hard drive (when the head keeps clicking rather than reading/parking). I remember thinking it was a bit odd but when one of my hard drives got stuck I did it and it worked (took two drops though). Of course I ordered a new hard drive and transferred the data because I knew I'd have caused some surface damage to the platters but I couldn't have got my data (without one of those super expensive data recovery companies) without that maneuverer and would have lost everything. Sometimes mechanical issues require mechanical solutions, not saying it works every time but it's def worth a go before spending money on a data recovery service.
My mother worked in IT and this was a legit solution at her work. (It was the easier version of opening the computer taking the hard drive out and slinging it, which was the earlier fix.)
NO it's definitely not worth a go! You could cause irreversible data loss, when it's otherwise intact. If you have valuable data, never risk it.
I'd assume it works due to the stepper motor getting stuck, and the shock of the fall allowing it to move again.
@@Twisterhere what good is the data if it's stored on a paper weight? And if the data was so "valuable" you wouldn't even consider this anyways.
@@foodhatesme You're calling a hard drives paper weights? And no it's not caused by a stepper motor, stuck heads are caused by numerous things such as dirt/lube build up, shock damage, failed pre-amps.
The usual first sign of a magnetic drive on its way out due to substrate failure is when Windows throws a delayed write failed error. You might also get loads of errors in the SMART error log. That's the point where you should already have made backups, and if not, get the most critical shit copied off ASAP because the drive isn't likely to survive the day. I've had several hard drives go out this way, and the fun part is that the failures are predictable months in advance if you do sequential read tests of the whole drive and you have sections where the read speed drops through the floor, as those are areas where the substrate is already failing, but hasn't quite gone completely dead yet.

My 2TB hard drive I bought from Newegg came in a big cardboard box with NO padding whatsoever. I’m wondering if I should’ve returned it now… It could done a barrel roll in the box if it was thrown hard enough, and nothing would’ve stopped it.
S.M.A.R.T. tracking is the only tracking i support with no questions. It can tell you how many hours the drive has been powered on and each time it has been turned to park or stopped as well as what Anthony mentioned.
You can also initiate SMART self-tests with smartmontools that are both OS-independent and log the results to the drive's internal SMART self-test log. Whenever I get a new magnetic drive, first thing I do is a selective test across the whole surface (smartctl -t select,0-max) so that if a new drive arrives with any bad sectors, it goes straight back to the vendor for replacement, and the drive is basically blighted at that point because the self-test results are baked into the drive's self-test log.

I got two decommissioned servers, each with 4/8 bays filled with 1TB drives, and obviously the pc hardware, raid cards and PSUs. Worth way more than the fifty bucks I paid. I have the drives in RAID with one redundant drive, and important data is backed up daily to my NAS (also used drives). The NAS data is backed up onto the RAID array. So if either one fails, I can simply buy a proper 8TB drive new and restore from backup, without much fuss. Yes, used drives are a gamble, but it's not too bad if you're smart about it.
So I know they say NOT to open a drive in a standard room because there's dust and particles in the air that can destroy it, but what about opening a drive outside? Since there's no dust outside would it make sense to open a hard drive on a table or something outside in an open field?
Outdoor air is absolutely full of pollutants. The amount of dust, pollen and god knows what else is in outdoor air in a field has to be astronomical. Clean room standards are incredibly exacting,. So no, you can't open a drive and expect to get it back if you do it in a field. In fact, if you open a drive at all even in a clean room you need pros to get the data off the platters.
My WD Green 4tb drive is a remnant from the first PC I built in 2014, and it's still working without errors as my main data drive for Windows. I've always left my PCs constantly running, with the option to turn off the hard drives during inactivity disabled, and it seems to be working for me so far. Yeah though, even though the SMART data is all fine (except for Load/Unload Cycle Count and Power on Hours), I'm planning to replace it sometime this year. I would've already done that if my data wasn't already backed up on an external HDD.
I read sometime that most HDDs either die within the first 2 years (manufacturing issue) or after the first 9 years (age)
I have a routine for HDD.
Brand new or used when received : check the smart and do a complete surface test with HDtune or HDSentinel to see if there are any errors
If errors are found : return to amazon
If ok : enjoy but always monitor and remember avoiding drop, vibrations and use a UPS
my amazon drives always go into my unraid server, and always 3 passes of preclear. If the packaging was...questionable...then 4 or 5 passes. I think i've actually only had to return 1 drive so far.
Hard Disk Sentinel says that my drive is nearly dead. It's at 9% Health. So many problems. And yet, when I decided to go and see files that are stored on those "dead sectors", the files are there and that sector still works. The 'wmic" test, says the drive is "OK"... So I don't know anymore...
@@juliettaylorswift How many passes did it take to decide to return that one drive?
@@p_x_ iirc before first pass finished. That was also back when the biggest exos was 14tb (but 12tb were still cheaper per tb)...so a while ago

What a coincidence! I was already running a SMART test of my hard drives 15 minutes before I saw this video ---btw DriveDX is a very good software option for Mac users
Thank you by telling me about crystal disc info you helped me save half of my data from failing with that device but it’s safe now because I’m trans ported it to my other healthy disc thanks so much
Backups are the only way to be safe and they are incredibly important, everything else is just a nice to have.
This is the type of video I genuinely enjoy! informative, not over the top and clear
Had a few failures over my years. Most were insignificant. Only one was slightly significant as it was a failure of one of my servers HDD's. Thanks to the combo of zfs and zed I got an email about the failure while I was sitting in school (this is several years back now) so I was able to just pick up a replacement drive on my walk back home and swap it in.
Hah, back in high school (almost 20 years ago...) my dad's work laptop died due to a seized drive... opened that sucker up in the cleanest area of the house, poked the spindle, sealed it back up, and used that drive and laptop as a server for four years. I only retired it because I wanted a more powerful machine. Sometimes these machines can surprise you.
You got lucky. Next time use a laminar flow hood. Any dust can murder a drive and there are millions if not billions of dust particles in a clean home.
Shout out to anyone else who watched this and immediately went to go make sure their backups were up to date
Drives sometimes do operations that aren't transperant to the viewer that could be mistaken as failure. I believe some have to do with getting rid of stiction for instance.
Compared to original IDE drives (the old school 20, 40, and 80 mb ones - if you were rich)...today's drives seem to be a much more dependable option.
Not sure if their MTBF data show any actual projected increase in lifespan, but anecdotally?
Yeah. they're better for sure.

Ohmygod I needed this. My PC is always notifying me to "scan for drive errors" every start up. I'm also experiencing stuttering whenever I play videos that are on the hard drive but not one's on the ssd.
I'm going to check out the softwares mentioned here. Thanks LTT!
Another thing is, just touch it on occasion, or check the temps if it has that. Drives can get warm and sometimes, near death, they get damned hot even if they aren't making much noise. Had one from work where the motor was failing, but was failing in such a way it was generating a ton of heat, but not vibrating weirdly, though it was also reading and writing ridiculously slowly.
Another great video hosted by Anthony! Also I love the blue backlight in the shop, it completely changes the atmosphere!
Anthony: The hero we never knew we needed, dont deserve, but is always there to save out butts from certain doom. Thank you.
did your hard drive die?🤣
SMART is (in my experience) totally unreliable. Disks die without ever giving an early warning through SMART. I just don't think hard drive vendors want to tell the customer that the disk is failing because they don't want warranty repairs, so it is not in their interest to signal early failure... Just treat disks as unreliable things and have a backup. No point in trying to predict anything here, really.
Nailed it
How would you expect smart to report on mechanical failures?
I just wish there was a solid program that could actually interpret the individual SMART values without needing background in what they each mean. Past CrystalDiskInfo's "Good/Caution/Fail" that is.
20+ years ago I had my hd kick the bucket... while tripping on 'shrooms. All was great with the world, pc crashed, hd was screaming inside the case, and it turned into my WORST trip EVER. So bad that I've never took hallucinogens after that. So I guess good things can happen when your hd crashes.
Induced K-hole HDD panic !!!
Give us a trip report
Hard Disk Sentinel is a program that I use. Once you start using it will start recording the "health" in percentage (estimate of life left) for SSD and HDD as well as let you see S.M.A.R.T and gives a estimated lifetime writes
Booted up my Quantum Fireball 20Gb from 1999 a few days ago. Still works like a charm, no harsh noises either. Perhaps newer drives are more prone to fail.
I've bought 4 "New Pull" HDDs over the span of 6 years and only one of them has failed 6 months ago, but granted it was the older one I bought. I'd say it's pretty safe to buy these types of drives, I've had OEM HDDs -especially from HP PC's and laptops- fail much faster (and way harder) than these used ones. Obviously YMMV, but I'd still say these types of drives are a pretty good deal IMO.
New 22tb drives were released yesterday, can't wait to order 6 of them and give my server more storage. I've got drives that have 11 years worth of power on time and still going strong....and others that die after less than 2 years

Why new drives that haven’t been tested in the field yet? Certain batches/models of drives are more prone to failure, so i typically wait for backblaze to have a significant sample size first, which usually takes a few years. My next drives will probably be a few of the Toshiba 16tb.
@@billybobby7607 no, no, I think my sarcastic reply whooshed you mate
As an IT guy, having experienced firsthand how unreliable spinning rust is, my instinct when someone asks me this question is to always reply with, 'yes, yes it probably is.' You can never trust hard drives, especially consumer level stuff (laptops/external drives etc).
I have hard drives from the 90s that still work completely fine even after heavy tests. I don't get it.
Well, also as an 'IT guy', I still put my trust in hard drives more than any other form of storage medium.
yeah they just die and die and die. SSDs have proven soo much more reliable for me. 50% of the hard disks my family and I have used have died, yet only two SSDs have died so far. One being a 2011 OCZ SSD that became well-known for being unreliable, and the other the cheapest SSD I ever bought, which died in the first 2 weeks. I personally use my SSDs very heavily and like to run them in RAID0 (I know..)
@@HazewinDog wtf kind of hdds are you buying? Are you throwing them around? I've never had an HDD die on me in decades of working with them.
@@n646n Same. Never experienced a hard drive failure within 20 years of using computers. Many second hand purchases. Cheap flash drives on the other hand
i actually have CrystalDiskInfo running in the background all the time and it notifies me if a problem has started with the HDD and fun fact: my (my old) Hearing aids have a t-coil mode that i can use to listen to the electrical signals coming off of the hard drive and i can tell if something is wrong with it...

Samsung SDD from early 2021? RMA it, these are known factory defects on models from January to April 2021. You will get a new one that doesn't age prematurely.
@@Grocel512 SSD in question is Samsung 850 Evo from 2015 so no RMA but I have to keep your comment in mind and check my Samsung 970s which I bought in 2021, they might be from that batch even though they still work perfectly.
@@Fortzon You should be fine then. The nvme products were not affected. If you had a SATA 870 EVO 2TB or 4TB you would have to watch out for ECC error rate and unrecoverable error rates. I had an affected unit (4TB) that I RMA'ed.
Last winter the NVME M.2 SSD on my laptop died for no reason, and it took a week to find a data recovery company and then 1.5 months to do recovery + 2 months to bring in order what has been recovered. After that day I always create backups on external drives, on a regular basis :)
How much did it cost?
@@LummyTum Back then it costed me 15,000 roubles (198 usd at the exchange rate of those days).
The same can be said for SSDs. The moment it has begun its use, it is on the slow path to failure. NAND flash has a limited write cycle count that only gets worse as more layers are added, and there are many electronic components that can fail on an SSD as they can on an HDD. Recovering an HDD is more likely to be successful though as the only things a person needs are the platters and the small chip that stores info on the specifics of that drive. Everything else can be replaced. An SSD is a LOT more complicated (data is usually spread randomly between chips for wear leveling because of the write cycle issue, can be encrypted, the controller must match, firmware must be the same, etc.).
Plain and simple, can't beat them for archival storage unless you go to magnetic tapes.
Would me fully depending on only 1tb SSD be a bad idea?
8:49 "trust me guys, hard drive failure sucks, unlike our sponsor: War Thunder..."
as someone who still today storage a broken 2TB hard drive and plays War Thunder every day I can say that youre wrong. hard drive failure does sucks, but nothing sucks more than War Thunder.
According to a decade of extensive testing by Google across its millions of datacentre drives, SMART is not a reliable, or even unreliable, measure of the health of a hard drive. What boggles my mind is that the two of the three most reliable measures are completely ignored: sound and latency. Sound is mostly indicative of bearing wear, though it also speaks to behaviour which SMART should be reporting if it's problematic, ie uncorrectable error rate, which leads to... Higher latency is by far the most important metric. As a drive ages it has an increased media error rate, and that leads to it re-reading blocks and after a simple re-read fails - re-calibrating. It's the re-calibrating that is the most obvious audible behaviour change with an unhealthy drive. The latency is easy to ignore, but you do so at your peril. Lastly, spin-up duration is also indicative of both bearing health and media health. In a sane world the OS would be keeping stats for how long spin-up takes, and when a trend towards longer duration is established, the drive should be powered off and you should be warned to duplicate it in read-only mode before its imminent demise. SMART record, but not log, spin-up time. Out of context of past behaviour it's nearly meaningless.
Yep shoddy video
They do talk about sound though
Can’t you use SSDs as relatively large-scale storage for home use, or is it more expensive?
SSDs have very limited write cycles, and it eventually dies when written to so many times. So while it theoretically have a long read-only life cycle, it’s not always the use-case.
SSDs are exponentially more expensive. a 20TB HDD costs about the same as an 8TB SSD. So if you have money to burn...
Uh I feel like I've read that SSD's being unpowered for EXTENDED lengths can lose data.
Good ones are between 4 to 8 times more expensive for the same storage and have a limited number of write times that is significantly inferior to what an HDD can bring to the table.
Sure, and that's probably the recommended strategy for most uses just because of power consumption, which I'm very conscious of during this heatwave. That having been said, it gets expensive when your storage demands exceed about 4 terabytes.
Probably in a world of how it used to be, but I have long been a massive fan of Spinrite. Has recovered more than a few hardrives and data that was otherwise considered too bad to recover.
2:14 High-capacity drives (10+TB) seem to perform self-checks that might also result in extra sounds.
I was going to buy an external hdd at my go to pc shop, also got some ram and asked for regular 3.5 hdds, the guy just handed me free 500gb hdds, got 4 of them for free, now i have 2tb of free storage, and i use it for backup! They were used on old servers, but were from 2014-2015, i got there in 2019, so i thought what the hell, they are free, lets try them out, still safely saving my music and photos till this day, shout out *undisclosed* pc shop! Your services were simply the best!
You never adressed what to do with a broken HDD. Do I just throw it away in the bin?
One thing you also need to be aware of is that when you want to use Enterprise disks in a PC you need to make sure the "power on reset" doesn't get a signal (mostly with older power supplies). When this pin gets power the hard drive will not spin up. Easiest way to fix this is using a molex to sata adapter.

Wish you'd added info to this video about the 'defect spare list' table used for bad block reallocation. It is typically 5% of the drive capacity and is one of the main reasons your 1TB drive comes out to ~947GB. Another part of that total loss is the mebibyte/megabyte issue, commonly referred to as 'marketing math'.
Bad block reallocation is normal because *infrequent* bad blocks are normal. If they occur too fast, too frequently or if the defect spare list is full, the drive will go into SMART failure. SMART failure can occur for other reasons, but these are the most common.
Firmware bugs can cause drive hangs and bad blocks (which can influence the SMART threshold tables), so keeping firmware updated when bugs are found is a good idea. Once a drive goes into SMART failure, there is no way to clear it (without manufacturer tools). Do firmware updates as preventative maintenance.

Meanwhile a friends dad had a hard drive with increasingly bad sectors, a semi broken MBR and no backup.
As soon as we found the issue we made a backup, but yet he still went on and did all of his work on that very drive for another two years.
Until his outlook database got struck. The recovery program didn't want to recover the files and he didn't save the correct file.
Luckily cloning the drive with ddrescue and repairing the database on the clone was possible and all of his work of the past 6 months was saved.
The new hard drive hasn't shown any issues so far, but the file system is still the same, so we are now trying to get away from that machine and sort all the data accumulated over the last 10 years as soon as he has another system to work with. Hopefully with a better backup strategy

Six years ago, my 2tb drive wouldn't spin up. Stuck it in the freezer for an hour, and it's been working great ever since. My Hitachi drives are 11 years old and still going strong, they're the best in the business!
For more than a decade I have used a multi-tier mirroring backup strategy. So far I've never lost anything.
Every computer in my home has a Data drive where the files are stored, I never use the OS drive for data, and that Data drive has a DataBackup Robocopy Mirror drive in the same case.
Then every computer has TWO external hard drives that the Data drive is also Robocopy mirrored to.
Then I have a NAS that has 32TB in it that every computer is also Robocopy mirrored to.
And finally, I have a large Google Drive where my most important files are backed up to.
I also have all of my code on a Microsoft Azure repository for an additional backup of my software development.
Using Robocopy scripts means that I can quickly double click on a batch file to perform any of the required backups to any of the destination devices.
This is very relevant to my interests as I've got a bunch of old hard drives I recently put into a computer after years of sitting idle and I want to see if they are healthy.
1. Well, if you buy used drive only way to be really sure about the state is to run smartmontools (smartctl) and extensive test. This will rewrite whole disk multiple times with particular patterns to really uncover any hidden bad sectors. (it could take days to finish based on capacity so ideally run it from smth like Raspberry pi with disk in USB docking box)
2. It would be worth to mention - especially on LTT - that raw smart data which are shown in SMART reporting tools (like Crystal Disk info) are manufacture specific, many times it's hexadecimal so need to be converted. And even when converted to decimal there might be values like threshold is 100 and actual value 120 it does not mean it's wrong some manufactured are actually using values as lower limit. Or value is not continuous but discrete. You need to find details on each manufactured how to interpret values.
3. Do the backup ;)
Dying hard drive? More like “Dude, watching these videos makes me feel alive!” I simply love how LTT provides us with so much useful and fascinating information.
I would advise against thinking of cloud storage as any kind of backup, unless it's on a "cloud" you really, really, own personally, like on a physical server in a datacenter. The problem with storing your data in the cloud is that you do not own your data anymore, the company that provides the cloud storage does. Even if it was due to circumstances beyond your control or even if you yourself operated in good faith, the moment a piece of data is stored in "your" cloud that they deem as violating their terms of service, they will block access to your data and they will not feel obligated to restore your access under virtually any circumstance. This is not because they are "evil", but because they will get in a lot more trouble than you will if they do not follow through on fighting wat could be illegal content in their cloud environment. The good adage stating "better safe than sorry" may apply to individuals and we as individual citizens may follow that advice, but the big companies that provide cloud storage to us and to other companies have no choice in that whatsoever.
wtf illegal content are you storing on the cloud???
Sounds like you're the problem here, buddy. I might not trust cloud storage entirely either, but if you've got nothing to hide your argument is moot.
@@skilletborne You are missing the point. It is not about what is illegal or not, it is about not owning your own data and not using the cloud as a backup for it. A file on your cloud storage does not have to contain actual illegal content to be deemed in violation of the terms of service and the moment you start using cloud data storage, you accept the terms of service of the cloud provider. They can deny you access anytime if they deem it necessary or appropiate. In other words: you are no longer the true owner of your data. This has been brought to civil courts on multiple occasions. An innocent picture of one's child playing on the beach, an unopened document sent to a unwitting receiver, etc., etc., all backed up to the cloud.There was no wrongdoing of any kind by the person whose account was blocked (or worse: one's family account, in which case entire families are hit by this). And in those cases, even though the judge recognized the fact that there was no actual wrongdoing, they were (legally) unable to force the cloud providers to restore access, because of the violation of the terms of service, unwitting or not, did happen. Legal scholars have commented on this and stated that there should be legislation in place to deal with these cases and protect the rights of the consumer in these circumstances. In most countries in Europe at least, such legislation does not exist. Not yet.
Also, the argument of not having anything to hide is a logical fallacy. Everyone has something to hide and everyone has a right to keep certain aspects of his life secret. Take, for instance, the PIN number to one's debit card.
Awesome video would be really cool to see more troubleshooting tips for commonish issues "is you're pc randomly crashing? Here is 10 ways to troubleshoot"
I'll be expecting the SSD sequel shortly 👌
(This is early onset) If you are noticing any errors what so ever. there is another option... after your diagnostics have shown there is a drive failure. You can use "HDD regenerator" this can potentially move information on bad sectors to un-allocated sectors... once completed a windows health check is needed through command prompt outside windows "chkdsk /f /r" ... once completed the drive should be repaired to an extent(data wise).... use a clone program to clone the data from the bad drive to a new drive. Hope this helps
what's weird is that i've never seen a smart warning in my life but my brother has. multiple times. usually for me i'll break my drive (by dropping it or something) before it fails due to smart errors. no idea why drives go from good to warning in that case - just time? overusage?
