seagate hard disk not detected. Does it spin? (what to do if you fried your drive by plugging in wrong power supply)
If your seagate hard disk not detected, first of all, power it on and listen to it with your ear right next to it. Does it spin?
If not, then it would be for one of the 3 reasons. Seized motor, unparked heads, or dead PCB (printed circuit board). There are also things like dead preamp, but on most brands of drives it would not prevent the spin up process.
I will begin with explaining what seized motor is. Seized motor on the hard drive is fairly common issue that you would find on Seagate hard drive generations 7200.8 7200.9 7200.10 7200.11 7200.12, as well as some hitachi/IBM 2.5” hard drives.
Seized motor would upon start up process with create a faint buzzing, and in some cases beeping sound. I would highly suggest that you seek professional help at this point. This is one of the most difficult tasks to perform on the hard drive, and without necessary equipment you will kill your hard drive in attempt to recover it.
However, these sounds are identical to the ones that the sound would make when heads are not parked properly. All modern hard drives offer touchless heads technology, meaning that the heads are never suppose to come in contact with the disk surface. In the past 3.5” hard drives used to park heads closer towards the center of the drive, and they would land right onto the platter surface that had air pockets to prevent sticking. That technology slowly started to get outdated and less reliable than touchless, so now hard drives park heads on the external parking ramp. Touchless technology offers more durability for the heads when the drive is off power. If it is dropped external parking ramp, that suspends heads in the air, is much better option than having heads sit on the actual disk surface. (this section is best to be read on our blog page here because I have pictures explaining the difference)
Unlike 2 issues above, dead PCB, will turn your drive completely silent. PCB failure would usually be caused by power surges, or plugging in a wrong external hard drive power supply. Dead PCB can be either replaced, or repaired on component level. Luckily, TVS Diodes would protect most hard drives PCBs for mishaps like this, so they need to be tested first. A transient-voltage-suppression (TVS) diode or thyrector is an electronic component used to protect electronics from voltage spikes induced on connected wires. Multimeter with continuity test option will quickly determine if you have a damaged diode or not. Ideally, if you detect the damaged diode it would need to be replaced with an identical one, but in our case since I just needed to recover the data from this external hard drive. After the failed diode was removed, client’s drive began to spin and get detected by our imaging equipment.

What if it does spin but isn't recognized?
Man you just saved my ass!! Thanks so much for doing this exact video, the pcb board was exactly what the problem and I got it fixed and saved a heap of cash because of your help. THANKYOU 🙏🏻
Mansion media excellent!
You just saved my life, I just fixed a 2TB WD hard disk with my whole life in it, thank you.
thats awesome!
Bro, this video saved me 400 bucks. Can't believe it was as simple as popping off a diode. Thanks!
You are welcome
@@hddrecoveryservices I need help with this SAS Hitachi ultrastar hard drive. It beeps once when plugged in, but doesn't spin. I'm not sure if this is a diode with the s marking code. Here is a pic link... ruclips.net/video/jH0GtQeJQhA/видео.html
Thanks so much! I accidentally broke the connector to the diode, but my drive spun up enough to get the data off it. LIFE SAVER!
That's amazing
Hi, I liked your video. However I am left with the question, how can the circuit work without the diode? I am scared to apply power to the board without the diode as there is a chance it can fry the board. Can you please explain the role of the diode in this instance and how the board can work without it? Thanks.
Thanks. dead hd. rubbed connections. replugged control and data boards >> WORKING. Thanks again.
interludo no problem! Glad it worked out
Did use magnifier and could spot corrosion. Lucky as I dont have adequate multimeter and skills to test and replace diodes. Thanks for your teaching.
Thanks man! It’s worked after removing one of the diode short circuit beeping was gone and successfully recovered our old data! ❤! All positivity to you
I'm having this exact same issue, removed the bad diode and tested continuity, all was well, but it's still silent. What do I do now?
Hello guy, I have a Seagate 4To who doesn't spin. I tried to remove the diode like you did but the disk still not spinning (I mesured 0.693 with multimeter). If I replace the entire PCB do you think it could works ?
Thanks for your answer !
Thank you so much! Removed faulty diode and it spun right up! Genius
My HDD spins but not detected.is there any other tutorial or solution for this case
regards
Yes, spezialized Hardware like MRTlap, PC-3000, RapidSpar, DFL
Same problem for me
Do anyone got any solved!
Thanks a million, the diodes on my 1TB barracuda were fine, but the pin contacts were dirty, cleaned them all and voila, now to save my files
Glad it worked for you
This video helped me to diagnose and get a damaged 1TB Seagate video hard drive (ST1000vm002) from a Rogers Nextbox 3 going again. The problem is exactly the same, a shorted diode (which did not test ok after removal). When I removed the diode the drive spun up and was recognized. I am surprised the drive board without that diode enables the drive to work. Can the drive be operated "as is" or should the diode be replaced?
Great video! Do you mind sharing what tools do you use to remove the diode? I have a same exact drive ( actually 3 of them! ) and they all died on me at the same time!
Were u able to repair your diodes??
after removing diodes and having the drive power up would you advise against re-using the drive or would you allow clients to continue using the drive as is? or is best practice to backup the data and get a new drive?
Thank you so much. I removed the bad diode now hard drive spins! I am able to get data backed up. Can a diode be purchased and soldered in? Or the diode crapped because of some other issue?
Revived my old 2tb hard drive using your method. Rarely subscribe and comment to RUclips channels but you deserve a commend and sub! thank you!
Thanks, this helped me retrieve data off a Sata 3.5 !
You are welcome
Great video! You are very knowledgeable. What’s your major and what you need to study in order to performed this kind of work?
Digital777 Studios I didn't learn any of this in school. Lots of trial and error and persistence. With data recovery you need to master PC3000 the rest will come naturally
@@hddrecoveryservices o que seria pc3000? obrigado!
what software do you use for checking the heads and making the sector by sector copy?
Thank you You are giving very good tricks we don't see anywhere else👍
It's my pleasure
Thanks for the video, it organized and elaborative.
I have a question tho, why didn't you replace the diode you removed ?
for data recovery process it is not needed
Are the reading heads any different on the same model of drive between SATA and ide, thank you for your videos and any help you can give
sometimes they would be interchangeable as long as they match up on specs. Different vendors have different criteria for parts matching
Thanks alot for your efforts
I have 2 TB seagate barrcoda
Stops working
I have another good one , same spec
When i use the board of the good one with the hard it give me error
No sound , no clicks while spinning
And they said to me you have to use the same board
Is their any chance to fix it
Realy i appreiate your time
Thank you
hi, I in similar case , I replaced diode and fuse , still without work .Can you tell me plz what is 6402 u3 chip think is broken too .Getting from Cuba
Very interesting. Impressed with your knowledge and very professional. Shame we don't have people in the UK like yourself. Not only a very nice guy and knows what he's talking about but also whiling to share his experiences and knowledge here on RUclips. You sir have a new sub. An see myself going through your entire channel watching a lot. I've had a few experiences with bad drives and loosing data so will be interesting to watch your videos.
I have a USB stick that says it read/write protected when it's not and has never been made protected. Just on day it decided to screw up and I lost so much. It's was only 8GB but I had 7 years of Xbox360 game save files and a backup of some important stuff.
One question I'd like to ask. Without going into huge detail I have a custom water cooler very high preformance PC and I've seen some people have a clear top, see through lid or case cover on there HDD so you can see it all working etc. all my SSDs are on show and I'd love to do the same
I see what you mean, I've seen those covers. Custom made out of plexy. At my old work we actually made one :). But once hard drive is opened it would be hard to keep it reliable, unless you run RAID1 in case it fails.
I've got an old SCSI Seagate Barracuda ST150176LC that won't spin up. No noise at all. Drive light on the circuit board does blink, but otherwise no activity. I located two diodes, both Motorola 933 1BL3 ZP, that appear shorted. I haven't removed them yet. Do they need to be replaced? If so, what equivalent diode can be used? I haven't found specs for these diodes. Thanks.
Hey i just sent a drive to outsource datarecovery services, and i KNOW for a fact the data on it is still good. The problem it has is that it TRIES to spin up but cant complete it. So i logically figured its either gonna be the PCB or barely possible the Spindle having a problem. I was told 3 times that all it would need is the $60 pcb swap, then they call and say "nope only data recovery will work"
But literally 30 mins before it just stopped spinning i WAS AT THE DAMN DESKTOP, the files are fine.
And you seem like an upfront sorta dude, how much would it cost for a PCB swap, or in the worst case a Spindle swap, i really really dont have a lot of money, which is why when he quoted me $600 dollars for data recovery, i just thought "data recovery?? why it doesn't need data recovery, the problem is its not spinning up"
I noticed that you have done a few of these videos (which are great) but they all turn out to be bad diodes. What about if the diodes are fine? I have a Seagate 500GB that makes no sound but the diodes appear to be ok. What should I be checking next?
No sounds could be linked to several things. Is this a HDD or SSHD?
@@hddrecoveryservices it is a HDD (7200rpm) Seagate Barracuda.
I have the same Seagate HDD which was dropped from around 2ft a few days ago. Since then it will not work. I can hear that the disc is not spinning but there is also a beeping noise. Did your HDD also emit a beeping sound when plugged in? I'm just trying to determine if i have a PCB issue or internal issue(such as stiction/head damage/spindle problem etc) thanks
Goodday, I've an 2.5inch bare drive as usb stick in my tv. After my son has dropped it really hard it ticks while playing movies. Did it died? it is freshly filled after format so no gaps from fragmentation
If it works again after removing the diode, could you use again your hard drive normally or do you have to backup it immediately?
Thanks for your videos! Any idea what might be wrong if seagate 2TB works just fine when detected, but... it's not detected all that often lately?.. It spins just fine, no weird noises. No errors in any test, SMART is ok, disk isn't too old yet (the newest I have aside from its replacement). And somehow BIOS just says says it's not there after being stuck on motherboard loading screen for like 30 sec. Swapping to other SATA doesn't help, other hdds work fine in its place. Tried to clear its contacts like you showed in this video, doesn't seem to help (but I got it detected at least 2 times after that). There's no data to save left, just wondering if it's something that might save me 2TB of space being tossed to trash.
Man i just go two of these 3tb seagates from a lady in town. Both are plugged into the SATA 6 pin power port on my EVGA and on only recognizes 3.8 gigs and the other does register at all. One makes that beeping noise as well while the other spools just fine but cannot initialize the drive due to an I/O error.

ST3000DM001
Have problems with Head 4... When imaging the drive I can see a pattern: where a batch of sectors wouldn't get read, then a long batch would get read, and then a small batch not read again etc - with equal intervals.
I ran /7 -> X through serial and got resistance values for all heads.
All heads reading around 300 (need to convert from HEX to Decimal) except head 04 (head 5) which reads 540.
Unfortunately I do not have access to hardware recovery tools like PC-3000, MRT etc... I've disable re-trying reading in firmware through terminal and can now quickly image the drive with HDDSuperClone without getting stuck at dead head for too long. But have a cleanroom, so will attempt a head swap after 5 healthy platters get imaged. If headswap will not fix the problem - time to send to specialists with hardware recovery tools.
I have 3 dead diodes 2 x 1ROZ and a small S41 on a seagate 4TB external drive that does not start up. the outside diode has power. I am a bit nervous about 3 removing them.
Would really appreciate an answer to this. You use special software after to look at the sectors etc, is this necessary or could you just plug it in and use as normal?
Im sure this is a stupid question but I don't get something. You touch red and black probes together to demonstrate the sound. Isnt this exactly the same situation when the current goes through the diode? In other words if the current goes through the diode and we touch the red and black probes on both ends of the diode it should be exectly the same as if we just touch them together (without the diode in between) and the sound should occur?
Not stupid, he was not clear about this: The basic function of a diode is to let current flow ONE way only....by "shorted" he means the diode lets current through both ways. The "arrow and a line" he mentioned is the symbol for a diode (can't type it here, just look it up and you'll see what I mean)...the arrow part of the symbol indicates which side is + and the "line" side of the symbol is the minus (negative) side. Current is supposed to flow from plus to minus, and if you test with the probes that way, you are supposed to get a sound...but if you switch the probes (put red on the minus side, and black on the plus side) and you still get a sound, the diode is no good.
Hi,
Liked the video, even though I have a question to ask. 🤔
I have a Maxtor 40 GB IDE 3.5" HDD which is not spinning.
I followed your example & (by reading a comment of yours) I placed the negative test probe lead on the cathode side of the TVS Diode (where the line or stripe is), while the red lead went on the anode side. 🙄
If I switch the probe leads I get the same reading on the digital multimeter. This isn't normal, right ?
Because the diode is supposed to allow current to flow in one direction, while blocking it in reverse. 😏
Because if I try the continuity test on the other TVS diode (switching the test probe leads), briefly I get a value on the LCD screen of the digital multimeter, but it immediately disappears (as it should). So the other one seems fine.
How do I get a replacement TVS diode ? Both are yellow in color. The suspected bad one is 336 16K 117. How do I interpret this ? 😣
The good one has writing 156 E P042T
Thanks for your reply in advance. 😊
Best Regards,
Can I know the Hardwear tool that you connect 2 hdds and softwear that you use to copy them?
i have the same issue but both diodes seem to have continuity. one reads .699 and one reads about .500. is it still possible one of the diodes is bad? should i remove them and test the drive without them?
Hello! It is necessary to repair the hard drive PCB, with this card drive will not start. Where to start repair, what do you say?
What I did. Checked suppressor - they are good, I changed the charge on obviously working and then the disc spins. What do more? Thank you in advance.
hi, I am not sure I understand the issue. So you got your drive to spin up with original PCB?
Absolutely superb demo sir very clear indeed and very helpfull indeed,thsnkyou loads,steve from the uk.
How do I find out where to get a new pcb board and cost. Mine is dead. Big chip melted.
This is somewhat HardDrive related but not exactly. I have a Buffalo Link Station Model LS210D0201 which I need to replace the drive, but I can not figure out how to open the case. I have searched on the Internet and I can not find any disassembly instructions for this model or anything similar. I don't want to break the case since it's functional. Just want to open it to replace the drive. Any suggestions?
I have the Seagate 3TB (ST3000DM001) and it spins up with no strange noises, but will not be detected, even with Disk Utility...what should the next step of diagnosis be? Edit: The drive spins up normally, but then stops spinning after just a few minutes. I already cleaned the contacts on the board (which were dirrrrty!!) but that didn't help :(
Any idea about a repetitive humming noise coming from the drive and the platters don't seem to be spinning. Windows on detect 4GB... it's a 500 GB drive. Windows want's to format the 4GB (I didn't). FTK Imager won't mount the drive either.
Drive failed during a power outage... suspecting a power surge. Checking what look like the diodes didn't find any shorts...
Is there any course I can take to be a data recovery professional?
youre genius brother....,my 2 Tb Hdd is function now....
:) glad to hear that!
So i plugged in a wrong drive and the diode broke, all i want from it is a couple gigs do you think its a bad idea to knock of the diode and to open it in windows? or replace the diode?
what was the software did you use to check the disk at the end.
Got a quick question...
I am a sad owner of seagate expansion desktop 100664987 rev b - 3TB version.
Lately without any sign drive just stopped working. Right now situation is: when connecting drive the computer I can hear that it starts spinning but after two-three seconds it just stops and nothing happens.
Do you thing that this might be something with device pcb or power supply pcb?
I know that this is only estimation and guessing without seeing device but I would like to know your opinion. I can upload video showing how it behaves if that helps...
Alternatively, what would be estimated cost of recovering data from that drive?
whats that little extra pcb that interfaces usb to some ribbon cable that goes to the hard disks extra pins ?
So where do the probes for the multimeter go? One on each diode or one on each side of each diode?
you need to test the diode. Negative probe goes on the cathode side of the diode, and the positive probe goes on the anode.
For clarity, all you did was remove the bad diode, correct?
yes
I bought a new seagate 1tb hdd and sometimes my pc doesnt detect it,sometimes it can.and it is freezing sometimes.What should i do? how can i detect the problem.What is the best tool,software for testing hdd? Thanks mate...
The mailman smashed that Priority Box because he liked it. 🤔
I have this exact drive and the exact diode tested bad, I removed the diode and the path tested good. The other diode/path tested good. The drive still does not spin up. What would you recommend the next steps be? I don't have a lot of internal experience on HDD Recovery, but I work with computer and am pretty comfortable around most things computer related. Any advice or assistance would be appreciated. Another note, I only have one of these drives, so I cannot currently take out parts from one and put in another. If that is a viable option, let me know and I'll look at picking another drive up. Thank you in advance.
you need to look for another possible short
HDD Recovery Services is another short an easier fix then another option? The stuff that you do is very inspirational and I would like to get more in to this line of work. Great content and video production.

Thanks so much! Opened diodes shorted 0 ohms and recovered my data. PSA modular PSU connectors are not standardized!
I took my external drive out of its casing and there is obvious burned marks on the sata bridge and not sure of the pcb. What would it cost to repair this or is recovery needed? Please let me know thank you.
you might want to check your drive in another enclosure first.
Hey My Good Man, I can't thank you enough for this Video. I am a Photographer/Videographer and also host my and my wife's Websites. I do keep a majority of my Photos/Videos on another HDD as backup but a lot of others stuff that I keep on this 3TB Barracuda Seagate Drive and the power for the dock stopped working after transferring it during a hurricane. After replacing the dock, the drive would turn on but not connect to the computer. I was going to replace the PCB board but wanted a way to test it before doing so. I was able to use this video with every step and that same diode was my problem. What I am wondering, however is how long will this HDD work without that Diode? Should I end up buying another PCB board to be safe?
it will last until next power surge Kato. 3TB ST3000DM001 are the worst drives to have, if you check their stats you will quickly find out about their over 40% failure rate. I would recommend moving your data to a safer device like a WD or Toshiba
Thanks for the info. Luckily, I have had this driver for a few years with a WD as backup; however during a recent move misplaced the power adapter for it. Is it the same output as the Seagate? 12v 1.5A. I also heard that WD have made it so that you can't remove the PCB. Is that the case?
hard to say about the power supplies. Usually they are the same, but plugging in the wrong one is what could have initiated your problem with the Seagate in the first place. WD Passport drives have USB connector instead of regular SATA
My 1tb external dirve spins but led not glowing and it is recognised by computer but not showing up in my computer or in disk management ? Please tell what to do. ?
hey dude , love your channel, now i have an exact 3tb seagate like the one in the video, it spins for a second when connected the stops completely. i got a multimeter and conducted a continuity test on the same two diodes but my multimeter doesn't have the sound like yours so i jus have to read the writing on the screen, problem is i have no idea what the hell am reading, it doesnt say 0.8 or o.5 , first diode returns 624 and the second diode returns 586 . what does that mean coz i am a complete noob with multimeters, which is bad and which is good on those two diode readings
If it spins up and down, then you have a much more serious issue known as a head failure. There are bunch of videos that demonstrate the process, but you need a professional help to pull data from the drive at this point
Hey man, I have the same drive, I just uploaded a video of the boot process. Is it toast?
My hard drive only spins slowly and gets very very hot is tehre a fix to this?
I have a ST2000DM001 that doesn't spin. I've cleaned the contacts with a eraser.
I've also checked the diodes. They are both not shorted. Is there anything else I could try?
Check the fuse if there is one
@@hddrecoveryservices Thanks for your reply. There seems to be no fuse on the PCB.
As the HDD doesn't make any sounds at all, the issue is probably the PCB right?
If I would replace the PCB for a new one, I would need to replace the BIOS chip on the new PCB for the 'old' BIOS chip, right?
Yes, the ROM needs to be moved
@@hddrecoveryservices Allright, thanks for your help!
Hi please reply
My usb power bridge on 2tb hdd is not picking the hard drive. I checked it separately the bridge led is on when connect to power but when connect with hard drive the light goes away and no sound nothing on hdd. Please suggest
Thank you for the amazing video, my Seagate ST3000DM001 stopped working all over sudden. when I plugin it into my windows PC via USB cable it makes clicking sound for couple of times then it stops. it shows only 3.86 GB space in windows. what are the cause? could you give me any advise, please? I wish you were from UK then I could have send it to you for fixing.
Exact same problem with a 2TB variant. Did you got any further?
So far no luck, already spent 500 pounds with data recovery , they replaced the head but it didn't fix hard drive.
EXACT SAME HERE, ANY SOLUTIONS??
Hi..
I need help ASAP please.. my hard drive does spinn and i feel the motion of the inner parts even though its not detected by either bios or pc or any other pc.. what to do???? is it PCB board or head problem or what..
So the hdd will turn on without replacing the shorted diode?
Technically yes
Which software was use to recover the data from dead drive plz send me link.i am from delhi
hello sir, my hard drive is spinning. do you have any idea what to do? it's light stays solid blue but the computer is not detecting it.
Man i really aappreciate this video it saved my but how long can I use this driver without the diode
:: Hi, Thanks for the upload. i have a seagate freeagent pro 1TB external hard drive, it is spinning but not detected by my computer. i already removed the case (enclosure) of it, to pull out the harddrive and try to put it in my computer but still its not detected. is it possible that the problem would be its board or should it be the disc?! hoping for your response sir. thanks ::
Jherson Bergonio usually if the Seagate drive spins up it is not the board problem. Could be problem with system files (aka firmware) or media cache. Does the drive make any abnormal sounds?
HDD Recovery Services hi! Have the same trouble. But the HDD make 2 beep sounds. After 5 minutes the bios and SO recognize, but couldn't get in it.
yo, I received a factory new drive from Seagate and the motor doesn't spin up. It gets detected in the device manager, sometimes also in the disk management without any storage showing up for it. I actually ordered two units, both of them seem to be from the same charge, although the PCB of the defective drive looks a bit discolored. I tried that one first in my external drive enclosure and it didn't spin up, so I assumed my external enclosure was defective (many reported cases of not detecting drives with more than 2TB of storage). I dropped the other drive in there and it worked without an issue, so I guess my one of the new HDDs is simply defective. Do you have any thoughts on that?
How much would it be for the diode remover tool and how would it be replaced, soldered or other method.
I am not sure what you mean by diode remover.
My mistake.
Kenneth Lantier you can remove smd things like a diode with a hot air gun or a soldering machine.
I know this is an old video,but I have this drive it died a year ago and I just got it up and running and Windows and Linux don't even recognize the partitions?
i have a dead hard drive, and i was hoping to recover the files(mainly photos,videos,and some backup messages).

Hi renz, maybe I can help. :) Samaritan Philippines
Hi bro. Do u still reply? I have exact same hdd like in that video. 2TB, can i just replace pcb with same model but different capacity with it?
Yes you can, but firmware needs to swap. EEPROM chip from original goes to the donor
@@hddrecoveryservices bios chip right? thanks bro. btw i have comment on your latest video. hope to hear your answer soon 😁
Hi there, I just recently had a storm at my house and I guess the surge protectors we had, were ummm not quite so protecting. I am pretty sure it is the PCB my drive is not spinning at all. Drive wd40efrx-68wtono.
I was wondering if I found and removed the removed the diode(s) and got the drive spinning again, could I just connect the drive back to my PC and back up the data? or should I try and find an identical drive and just replace the PCB?
Thank you very much for your video!
Both my main drive and back up drive got fried. All my music for my albums and artwork and then some is gone if unable to retrieve.
Also, this may be a dumb question but I have a PCB from a different WD drive. The drives are completely different in specs, but the PCB is same shape, connections, and so on...I know its not same drive so I am not sure what the firmware would do to drive from that PCB.
Scrub a copper penny with a pencil eraser, then look at the tarnish a week or month later. Also touching the cleaned contact with oily fingers will cause contact problems later. Maybe good for return repair later, easy scrub head preamp contacts again to fix until next return..
This di right here is Just so you can pull the data out and toss the drive. It is not a long term fix.
Hey I removed the diode but the multimeter still beeps. Did I do something wrong?
then u have anonther component that short out...find this!..i u remove the diode, check if the still shots out or if the diode could be ok! i have the same drive with the same problem but my doesnt spin on...i removed the bad component but still not spin
thank you, a question, what happened if we keep it with just one diode?
next time there is a power surge, it will hit something more vital if you don't replace the TVS, otherwise its fine.
does replace pcb / board also fix slow reading hard drive? I have WD home studio hard drive which suddenly very slow reading and some files cannot be read, thanks in advanced
Did you not have to replace the failed diode...
Not if you just want to save the data and don't care about the long term protection of the hard drive
My tvs diode is not shorted and the disk does not spin. What do I test now? Should I renove it anyway?
You need to check 0ohm resistors by power connectors make sure those fuses are not blown
Hi, I have this problem with a Seagate ST2000DM001 - I got the same short on one of the two Diodes. I removed the diode which had shorted, but it still indicates a short across the pads once removed - and the drive still will not spin. HELP!!
Paul Archer Paul at this point your best bet would be to locate an identical PCB part number and swap out the eeprom chip from your failed board to a new working one. That will adapt the new board to work with your hard drive. I don't go beyond troubleshooting the diodes on these when it comes to failed/shorted boards because my inventory of donors is really good and it is just way easier to pull the donor than try to figure out what is wrong on component level.
When i clean the board and connections,diodes and caps are not shorted.The drive are not recognized i n Bios,sometimes cause to freeze on start.What may be wrong ?,help.
hi i have the 1tb baracuda it power up and spins with no funny noises , shows up as being pluged in with usb but doesnt show up as a usable drive if i go to drive manger it doesnt show up , im thinking its the pcb on it any ideas?
I have this drive and it died! spins up fine - sounds normal - windows and bios do not see it - i removed the pcb and cleaned the contacts - same problem - any idea what could be wrong?
Hi I have a hardisk with the Rom (Bios burned - in the sense that PCB's rom is missing)
Reason I had buying a card to do the swapping but the repairman lost the original card)
Do you think it is possible to recover my Seagate Hardisk?
In short, the HD has never been opened and card that has does not have the original BIOS

Hi HDD. My Samsung D3 External Drive 12 V adapter cord was accidently cut (got caught in a door) I had just used the device and it was working perfectly fine. A friend suggested that I buy a new adapter on Amazon. In the meantime I went to Radio Shak and in-store the sales guy inserted a universal adapter on 12 V setting. It did not work and immediately the drive started to smell from the vents. A slight burning scent of course. I eventually got the old adapter cord repaired by an electrician. Now the Light to the front is just blinking, the HD is not spinning and the computer is not reading the HD.
I am desperate! What do you think occurred? Sounds like a deaf PCB. I have a lot of important Client files on the drive. I need your help

What software are you using to turn heads on and off?
JGAN96 data extractor, it only comes with PC3000. Not cheap but the best tool hands down
I have a Seagate where it no longer recognizes the HDD password, bedsides a platter swap at technical lab can switching the exact PCB get it working to get the data off??
if the drive spins - PCB is not a problem
