HDD GURU FORUMS

Hello,
I'm searching a PCB for WD15EARS-00MVWB0 and shipping to Germany. I had the problem for unplugging the USB connection on writing. After that the drive was known and the partitions looks like correct. After a while the spinning drive stopped and no communication with HDD was impossible. From a good friend i got a changed PCB board. Its nearly the same but not function correctly. The HDD was selected but no partitions was shown. I have Win 7 professional and the HDD management shows the drive but not initialized. The low level formatting was impossible while drive security is on. The different between the two boards are small:

Only the memory chip and the main chip have another numbers, elsewhere all the same.

Original board: 2060-771698-002 REV P2; on label: 2061-771698-102 AA XC BE98

Changed board: 2060-771698-002 REV P1; on lable: 2061-771698-102 04P XT BE46 TQ1U80003040 1043

What is the different? The spinning drive works correctly, the sound is OK, but i can´t work with it. I hope my english is OK and anyone can help.

The serial flash memory chip at location U12 stores "adaptive" data that are unique to each drive. You need to transfer this chip, or its contents, from patient to donor.

Does the original PCB still spin up the drive, or is it completely dead?

Hello

Thanks for the advice. The original PCB still spin up the drive. That´s all. If I understand you correctly you mean i changed the serial flash memory chip from original PCB to changed PCB. Simple unsolder, is it right?

I expect that others will tell you that your problem is most probably not a PCB fault.

That said, the first thing I would try would be to use a soft white pencil eraser to gently scrub any oxidisation from the preamp contacts on the PCB.

If you want to try swapping the PCB, then you will need to desolder the chip at U12 on your original PCB and solder it onto your replacement PCB. That's something your local TV repairer should be able to do.
