I have received a hitachi deskstar, family SLA360, pcb is dead and a few components are missing. Someone has already had a go at it. I have exact match of Hitachi deskstar, change NV-RAM (I believe its NV RAM chip) but patient hard drive remains BSY.

Does anyone know if there is embedded rom or something else which needs to be done in order to get donor pcb compat?

I look forward to your wisdom...

not familiar with this family. Sry.

Do the first two lines on the PCB sticker match?

drive details. Model, Part No, MLC all the same. Patient is Aug 09, Donor is April 09. PCB codes are

0A29989
BA3129

and

0A29989
BA3263

In my opinion it should be a match but the fact the patient is made after the donor is Probably what is causing the problems providing NV RAM is present and correct.

Anyone have a donor made AUG 09 and after?

The fact that someone else had the drive and that some components from the PCB where missing when you received the drive, could indicate that PCB was not the original problem. Do you know the original symptoms of the the drive. Was it also just spinning but busy? I would guess NV-RAM issue and needs to be rebuild.
