Seagate Barracuda LP ST2000DL003 burnt smd component on 5v

[B1r0]

Hi all.

I've been stupid and, please don't ask why , I switched the 5v line with the 12v on the sata power connetor.
Now I have "4" of these drives with the circuit board unusable.

I believe (and strongly hope) they can be repaired, but I'm not able to identify the components that I burned.
I think they can be resistors or fuses (but I never saw a smd fuse that small before).
Reading around the forum I also think a TVS diode is gone (when tested the diode there is current passage).
If the resistor were zero-ohm shouldn't have blown, am I right?

Anyway please have a look at the pictures of the boards and one picture from a blog article that shows an intact PCB.




Any help in identifying the broken components will be much appreciated.

I'd like to recover these drives if possible but I don't mind about the data that I have a backup of.
I've seen on the Internet replacement boards but they ask $50 and I have to send the faulty one to get the data from the eeprom.

Thank you
Biro

$50 for a pcb + rom transfer is really a bargain.

It is a bargain indeed, especially if you need to be sure to recover the data from them.
But I'll have to buy 4 boards and no need to recover data from them, therefore I don't want to spend that money when I can just buy new SMD components (or scavenge from old drives) for few quids.
I'm no electronic expert, but I know how to use a rework station to solder the board back together.
Cheers.

That board looks heavily damaged, and I'm almost certain that if you put new components on it you will new weird faults.
Not to mention that your preamp is most cetain gone with that damage, but only a new Pcb will tell.
