      louis, u will love to hear, that western digital (seagate probs too) puts planned obsolescence in their drives.
      western digital sets up their consumer drives to have insane load/unload cycles like every 12 seconds for example.
      the heads are designed to only deal with a certain amount of load/unload cycles, 300000 for example.
      so having insane artificial load/unload cycles will result in people's drives having a much higher failure, than they actually should, meaning people get to throw more money on the 3!! only 3!!! hdd manufacturers of the world....
      there is a tool to fix this bs on at least old wd drives called wdidle3, which fixed the issue on a friend's drive i got for free, not sure if that tool still works on modern drives.
      but isn't it lovely, that just like apple with their soldered onto motherboard ssds, hdd manufacturers don't give one fuck about consumers and go out of their way to get the drives kill themselves.

    Oh how this brings back memories. I like your head comb. I used to grab the head stack with tweezers by the slot located just behind the head comb. It may be easier than grabbing the heads from the top of the head screw. Most of the work we did was performed on a work bench then we imaged under a clean air booth. We used a black marker to identify "parts" drives and if any heads were bad, we would make note of it on the drive cover. The PC3000 has come a long way since I stopped recovering data. Good job!

    Really interesting to see steve prefers WD. Over here in the UK our shop sees so many WD drive failures in 2.5" laptop drives within the first 2 years, more often than toshiba or seagate. We replace with seagate and hardly ever get a return. I will probably get roasted for saying this but this is our honest experience.
    I really liked this video, more please!

      We ordered a batch of 30 Seagate hard drives for a NAS trying to save money. 1/5 drives were DoA. Three of the working drives failed within six months. Two of the six replacements for the DoA drives also failed within a month.
      I've also bought Seagate as a cheap backup only to have it fail before the drive I was backing up.
      Maybe the drives in your inventory like you or something or I broke too many mirrors as a kid.

    A couple questions here:
    1. Do I get it correctly that it's basically a lottery whether each specific head works well enough after a replacement? Why so? Also, is there any head calibration data on the PCB/platters that needs to be copied from the donor?
    2. Is it possible to grab all the data from the working heads before attempting another swap? Is it possible to feed the service data into the drive from the outside if head 0 happens to not work after a swap?

      good questions. even as much as I know, I'm not sure. But everything you said sounds accurate.
      yes there is head calibration data and he seems to have skipped that part.
      yes you can swap once, read what comes, and swap again and hope for more.

    Some old hard drives could be surprisingly dust resistant. I had an old maxtor drive (i think, could have been a late micropolis but I don't think so) in a machine at the office. It was loud, really loud but as it was working and stuffed into a cupboard we didn't really care. I can't remember what it was used for, but it was kept in use for a long time. Eventually the machine was rendered obsolete and before scrapping I looked it over for usable parts. There wasn't much, but as I dug into it I suddenly felt air moving across my fingers, but there were no fan anywhere near. Turns out there was a large hole in the top cover of the HDD through which you could look directly at the edge of the platters. It had originally been covered with a sticker, but someone had peeled it off years ago. It was from this hole the air I felt was blowing. Covering it up with my finger made the drive sound like a normal HDD without that weird whooshing sound. So this drive had been working for more than five years with a hole about 12 by 4 millimeter in the top cover. And this machine was totally disgusting inside.
    I found it fascinating that it was working at all, so I kept it around to use for simple testing and it held up for several years of intermittent use and never lost a byte before it eventually ended up in the dumpster as it was simply to slow, to small, and as a IDE drive totally outdated for any practical use of any sort. Never did cover up that hole though, and I have no idea how it survived for so long.

    The PC-3000 is the real hero here (and quite costly too). Its accessing the drive in special ways, reading the HDD System Area, internal ROM modules and all the calibration information, and other things. Just swapping heads + PCB and using ddrescue on linux would not result in as much success.

    Generally, if you need to do everything correctly, you first need to load/replace to the test engineering firmware, leave only the translator in memory, disable hardware and software write process , logs, smart, expand the ECC processing and then check the operation of the preamplifier and check the MR element (state response) and read all the healthy heads.
    Then start reading the data on defective heads, and then if it required adjust the parameters of the reading MR current for better read the bad sectors by the degraded heads, and if you need after all replace the heads.
    The PC3000 does not support the new Seagate and Western Digital (hitachi PCB:LSI, Avago) models. To do this, use PC3000 plug-ins library (separate developers in data recovery community) or use factory utilities for obtain better results and in some cases to unlock the hard disk firmware.
    If someone needs help and recover data from 4-5-6-8-10-12-14 terabyte of disks, please contact me. We have factory tools from Seagate and WD, Sandisk.

      personally I think you know more than him :) the head calibration is missing from this video.

      @@mrlithium69 Yes usually if heads was swapped it have close or worse reading parameters.
      And in most cases it reading slow or have some unreadable places.
      In this case need adjust only reading parameters in firmware, for this type WD in modules 40-4X. Or even better if there no surface damages start script from firmware to calibrate heads. it collect all new heads parameter by zone tables and then possible read all surface and data like it was with original heads. Also possible make reading auto correction much wider. Because maximum reading MR currend not exceeding 80% of maximum possible. many data recovery services have problems with heads swap and they usually thinking it heads not match. really if heads the same or even from later hard drive family then heads parameters have more difference than original. Some hard drive wich have one head reading trouble just enought made some correction for one head adaptives and this head can read data again. Some head have degradation (parameter shifting) during life cycle so it possible shift back to work point parameters and it can be read data again. Adaptives for write it is different part of firmware . we do not need it for data recovery process.

  • @aBoogivogi
    @aBoogivogi 5 лет назад

    Very interesting video. I will pester you with a couple of technical questions if you don't mind :)
    - How does the bench function. Is it just a filtered intake that releis on no other particles entering it any other way due to the increased pressure inside?
    - Can you do anything about the new helium filled drives?
    - Is there any connection between drives sound level and quality? I have had multiple WD drives and in my experience every WD Black drive has always been far more noisy then the WD Green and Blue drives out of the gate.
    - What is your opinion of HGST drives? In my experience they seem to be pretty close to WD in terms of resilience, but a bit noisier and with worse SMART support in some cases?
    - Do you check the SMART status of drives that come in (would be a kick ass way to gather data and validate how useful SMART actually is) and does it have any value in terms of error detection and diagnostics in your opinion?

    • @mrlithium69
      @mrlithium69 5 лет назад

      1) yep, positive pressure and ultra fine filters basically
      2) their lab would have to be equipped to refill the helium
      3) a drive getting louder like that means the spindle motor bearings are worn down and this can be replaced if need be. The Black drives spin faster and in all likelyhood use the same bearings so they are just outright louder, even new.
      4) HGST is fine, otherwise up to you.
      5) If you know how to interpret the SMART data, yes. My primary go-to metrics to look at are ReAllocated Sector Count, Current Pending Sector Count, Uncorrectable Sector Count, Hardware ECC Recovered, they all give a picture about bad sectors, and then drive lifetime data like Power-On Hours, Start/Stop Count, Head Flying Hours, Load/Unload Cycle Count, Temperature (max) to get a general idea of how rough the drive was used. These terms came from a Seagate drive. Every manufacturer uses different terms and different raw data values, so it gets quite hard to read and compare unless you get in the habit of reading the SMART data like a daily news report to see what changes over time naturally and un-naturally.
      GL@!

    @TheGoodContent37 5 лет назад

    I love you for this. I'm a computer engineer that once had to pay a fucking ton of money to get some files recover. Later in my college career I learned that the only thing the drive needed was a swap of a very cheap board. Fucking greedy people charged as they fucking made reverse engineering to the drive or something when they changed the board from a donor disk and swapped a chip.
    I had never understood why this kind of service hasn't been normalized yet. It's so freaking easy!

WD green is 5400 RPM and has a high fail rate. (I used to handle warranties in a computer store) and the most returned drives, Seagate and WD Green.

    I’d like to try what you demonstrated.
    1) How many platters does my hard disk have ? Want to know the answer to this before opening my drive.
    2) I ask this because I need to buy comb as well accordingly. Any suggestions on this too?

    @Louis Rossmann Thanks a lot for great video! It's probably off topic, but I'd like to ask you if there is a chance to bring back to usability a drive (3,5 inch, WD 1TB Blue) which reports CRC error? Not found in Explorer of Windows 7, but then in Disk Manager it is found, I was able to remove partitions, put a single one, but upon an attempt of formatting it cannot find the drive due to CRC error so all the articles on the net to do the checkdisk are just pointless at this stage. Drive spins and based on sound it reacts when connected to the computer in a proper way. Is there a chance to save the drive or I just got a coffee mug holder?
