I have a WD800JB-00CRA1 that is not anymore visible in the bios.
I tried a pcb from an WD600BB-00CAA1 and the drive became visible.

Can I use this pcb with some adjustments?

What are the PCB numbers for the original and donor PCBs?

pcb number from 80gb: 2061-001102-300B
pcb number from 60gb: 0000-001092-300J

When I use the 60gb pcb on the 80gb disk i can see the directory structure (in TestDisk), but not the files in the directory's.
A scan (with TestDisk) results in bad sector reading.

Interesting that the folders are seen with donor board. It seems the ROM adaptives are close enough that it's reading. I think the problem now is bad sectors and partition corruption. The best step is to make a complete image of the drive, then scan that image using R-Studio, or similar data recovery software. For imaging the drive, you may want to try something like ddrescue.

Thank you very much for your answers!


But is it still better to find a pcb from a similar disk (with similar pcb-numers?)?
Or can I use this pcb to salvage data?

(bcometa: i like to send you a pm, but i can't send because to less posts.
If you send me a pm, maybe I can reply on that?)

I believe since even if just some of the data on the drive can be read, the PCB must be okay. I *think* (and may be wrong), that if the ROM wasn't compatible enough, NO user data would be accessible.

The problem occurred when I connected the drive to an ide-usb-adapter, minutes before it was just running Win + programs fine (as far as I know).
Is it possible that bad sectors and partition corruption is an effect of, for example, high current?
With the problem-pcb from the 80gb the drive was not spinning right, it was spinning on-off on-off with some sounds from the heads.

I think it's more likely the ide-usb-adapter messed up the original PCB and perhaps that messed up the partition. The on-off spinning could be symptoms of a "bad pcb." Try the full data recovery scan with some different software tools after imaging the drive.

Ok, thank you!

There are NOT ROM adaptives for this model!
You should know that...

According to donordrives.com, a chip swap or firmware adaptation service may be required, for whatever reason:

Is this an error? :?
