Looking for a specific WD Black 2TB drive

[whoope3]

Good day all!

My WD drive has died on me, and I believe that the PCB needs replacing. But I will need the EXACT same PCB in order for the drive to work (i got one from ebay, but it differed slightly so it did not work).

So I just wanna ask if anybody here has this drive? If so, drop me a PM please!

Do note that everything has to be the same. Even the DATE of the drive! Drives manufactured on different dates have changes and updates done to them, even though the models are the same! But serial number different of course ok lah

Model: WD2001FASS-00U0B0
Date: 07 Nov 2009
DCM: HBRCHV2AB
LBA: 3907029168

PCB: 2060-771624-001 REV P1
PCB Sticker: 2061-771624-700 05PD9

I don't think you can just swap the PCB.
I read need to swap the BIOS chip too.

I only have WD2002FAEX.

What causes your hdd to die? Wat are the symptoms now? How did you decide that it is the PCB that is faulty?

Replacing the PCB is not the end if the story. You'll need to replace the ROM and also ensure that the firmware are not corrupted or missing. Otherwise it will be a waste of your efforts.

Yes I've done a bit of research on the BIOS chip, or also known as the U12 chip. Luckily this drive does not have one (the U12 socket is empty), so a direct donor swap should be possible.

No idea on the cause of death, only the symptoms. The drive is able to properly be detected and read, but performance severely degrades after a few minutes of use (read/write speeds drop to ~5kpbs). Since there are none of the mechanical noises of death from it (ticking, whirring, buzzing, etc), I assume it's an electronic failure. As for the ROM, see above.

It may not be a 100% surefire way of fixing the drive, but I'm willing to try

Since the drive can be detected by the PC and it is able to spin up, it is not an electronic failure. Change the PCB will not fix your drive.
Your drive most likely has one or more heads failure or the platters has bad sectors caused by the head failure.

I see.. Here's the exact process of the problem:

1. Drive detects fine when booted up
2. Files can be accessed/written at optimal speeds for the first 1-5 minutes
3. After that, drive performance degrades to something like ~5kpbs
4. Files in the drive then become unreadable
5. Restarting the computer brings me back to #1

Wouldn't a head failure give mechanical noises? I ruled out bad sectors because that it wouldn't cause the major slowdown for the WHOLE drive.

Your drive is dying... Try to use a docking station to verify...

Not all head failure give mechanical noises. Sometimes the whole head becomes dust and disappears. Or it becomes unstable and weak magnetically that it cannot read the data. In these cases, a normal person will not be able to hear any different mechanical noises from a good drive.

Bad sectors will get your disk to slow and hang as it tries and tries to read the data one sector after another. With numerous bad sectors, your disk appears to be stuck. Repeated trying to read a bad sector may cause the head to be overheated and burnt off becoming dust and scratching the platter in the process.

why dun u just use CrystalDiskInfo and take a look at the health status?

if its bad sectors issues, u would probably see caution or BAD. won't take u more than 1minute.

rather than speculating/wasting ur time to find/change logic board. etc etc.
