seagate ST360021A

[nobug]

Hello

I am new to this forum, I have been reading and looking for a solution to my problem. Which is a dead st360021a, it started with a power surge that fried the power supply, that was hooked to a UPS? after replacing the power supply the pc would not start or post, after finding the hard drive was the problem it was replaced and pc is fine. I want the data off the non working drive. If I
plug the drive into any pc it will not power up. So I figure the logic board is shorted. I bought a drive off E-Bay. Same drive but different firmware I swapped logic boards, now the drive spins up but isn't recognised by the bios. What would be the best way to get the drive working? I don't want to send it out for repair I prefer to do things myself.
1:Try and upgrade firmware of different logic board to the version I need, or will that even work? I read something about serial numbers not matching.
2. Try to repair short circuit on original logic board.
3: Swith the rom chip from old logic board to the one I bought.
Any feedback would be greatly appreciated.
Thanks

Hi,

I also have short circuit on my printed circuit. I found out which part it is, but I don't know what it is?!?! On my opinion it is a "Zenner" diode (it is positioned by the power connector), but I'm not sure. Does anybody have printed circuit layout. I need to know how can I replace my broken part?

Hi. I have exactly the same ST360021A problem as "nobug" here:
I have a blown PCB firmware 3.19 and I can get disks spinning with a firmware 3.75 board but no data access. Is there any way to get this going without searching the planet for an identical PCB?
