Repair MAXTOR STM3160215AS

[pongino]

Hi guys.
I've done a mistake. I used an ide to sata converter but I put it in a wrong way, so my HDD burned.

How can I recognize if there is any shorted diode? I put some photos of the board.

How can I try to recover it?

My HDD specs are:

MAXTOR STM3160215AS 160 GB
DiamondMax 21
S/N: 9RA3E45D
PN: 9DS112-327
Firmware: 3.AAD
Date Code: 08175
Site Code: TK

Thank you to everyone helps me

Thanks a lot for your fast reply.
I read the FAQ that you have linked to me and I'll test the diodes soon.

Can you show us a picture of your IDE to SATA connector. I am so curious how it went on the wrong way. I got a lot of ones here and they only go on one way this one seems very strange to me that you can make it go on the wrong way.

The picture of the cable is



and....yes, the IDE ones looks like a "D", so it seems impossible, but you can connect it on the wrong way

I've removed the two diodes (look at the photo below) but the HDD is still dead.
There is any chance to recover it? Can I remove something else?

So what was the result of your diode test? Which diode, if any, was shorted?

If you decide to replace the board, then be aware that you will need to transfer the 8-pin flash memory chip in the top left corner of the PCB to your replacement PCB. This chip stores unique drive specific information.

Some PCB suppliers include a transfer service for US$10. Otherwise your local TV/AV repair shop should be able to do it for you.

BTW, when you say that the HDD is "dead", I assume that it doesn't spin up, or attempt to spin up? That is, there is no noise or vibration?

The meter displayed 1. I decided to remove them anyway.

There is no noise or vibration and it doesn't spin up both before and after the removal of diodes.

If the reading was "1", not "1.0", then this indicates that the meter overranged on that scale. This would mean that there was no short circuit. A "1" is the same reading you would get if you held the probes apart in the air, ie an open circuit.

That said, it could be that the 5V TVS diode went open circuit as a consequence of swapping the +12V and +5V inputs, if that is indeed what you did. I would test the diodes again, this time on the diode range, and in both directions.

Thanks for help but I've already removed the diodes, so I can't test them again.

If I found an "exact match" PCB (and not a similar ones) then I've to do the memory chip transfer anyway?

Is there any test to understand if the hard drive is still working without changing the PCB?

Like I've said the hard drive doesn't show any vital signs both before and after the diodes removal.
