HDD won't spin (might've had voltage spike)

[Silvu88]

Ok, thing is : Friend of mine got new modular psu and accidentally plugged sata cable to 6/8-pin gpu rail (in psu) to hdd. Now hdd wont even spin. pcb board dead? There is no visible damage on pcb, there were no smoke coming out of it as i heard. Is there any change to repair pcb or do i have to order identical one and start fight with firmware adapts etc...?

Thanks in advance!

Edit:
Model of the drive is ST1000DM003
PN: 9YN162-300
FW: CC49
PCB : 100664987 REV A

There will probably be a shorted TVS diode plus two open circuited zero-ohm resistors.

If so, remove the diode and flow a blob of solder over each of the associated resistors.

I suspect that the 5V TVS diode will be shorted.

Seems it's exactly this way. Tested with multimeter and 5v diode lets through and lower two zero-ohms block

Thank you very much for info. Finally got my hands on soldering equipment and got bit of courage to try. Removed 5v diode and made blob over both of zero-ohms, works like a charm. You've made two people really happy, Thanks!
