Replacing PCB on WD2500

[mmatos]

Hello,

After much googling and reading the forum, I believe I have the answers I'm seeking but just wanted to be 100% sure before moving forward.

One of my clients had a power supply blow and take out the motherboard and hard drives. His machine had two WD2500 drives, both of which were impacted (see image).

Going by the sticker on the PCB, they are:

2061-701335-C00 AE
and
2061-701335-C00 ADD4

From what I've read, I should be able to replace the PCB with any

2061-701335-C00 as long as the EEPROM (U12) is transferred to the new PCB.

Can anyone confirm this for me?

Thanks in advance!

Yes, that should work. However, you should probably match the number on the PCB artwork (2060-701335).

This supplier includes a firmware transfer service for US$20:

It should be fine.

Just a note that you might have further issues though. If you get a compatible PCB and move the U12 over, and the drive spins up and clicks, it could be that the preamp for the heads is fried, in which case it's no longer DIY.

When I'm looking for a WD PCB I always use the label printed on the board, not the one on the sticker. For example: 2060-771640-003 REVA (taken off a random WD drive lying in front of me on my desk).

It's always worked for me, as long as the only issue was the PCB, and you transferred the U12 correctly. The first few U12 swaps I did I messed up, didn't seat it down properly on the new PCB, and the drive wouldn't spin up lol. Crap soldering skills.

Good luck.

PROPER DIAGNOSE is resolutive !

Okay, so I got new PCBs and did the U12 swap. The BIOS detects the drive as a HAWK with 8GB capacity. Any thoughts?

The problem is elsewhere...

Problem is indeed elsewhere. Are your replacement PCBs a perfect match, do the board numbers and revisions match the patient PCBs? Sounds like this has gone beyond a DIY job.
