Suspected burnt PCB on ST3160815A

[jonyp]

Hi guys just come across this website.
Keep up the great work.
After reading up on a few posts here I suspect that I may have a HDD with a burnt PCB.

Customer brought in PC to copy files over to a laptop.

Plugged in the PC then bang. PSU blew.
Replaced PSU.
Removed all devices/drives and reconnected onebyone.
PC turns on until HDD plugged in.

HDD smells like burnt plastic and doesnt spin.

Dead drive:
Seagate barracuda 7200.10 160GB PATA
MODEL- ST3160815A
P/N- 9CY032-305
FIRMWARE - 3.AAD
DATECODE- 08427
LABEL on PCB- 100431057 H C8394WY4

In the process of finding a suitable donor drive, but all I have in stock is the following.
Seagate barracuda 7200.10 160GB PATA
MODEL- ST3160215A
P/N- 9CY012-305
FIRMWARE - 3.AAD
DATECODE- 09485
LABEL on PCB- 100431059 M C947F7KW

Wondering if the drive I have would be a suitable donor drive for PCB replacement.

Thanks,
John

Check the TVS, search for "TVS" on this site.

I had a read up on the diode prior to posting, but I thought I'll hunt around for a donor drive incase it fails.
The PCB is upside/down so i will need to remove it before getting to the diode.

Any special requirements to remove PCB apart from clean environment, static mats, ground strap and power from another isolated PSU.

pcimage,

Thanks for your re-assurance and help regarding the TVS. It was burnt to a crisp, files have been succesfully backed up.

Note to self: Remember to tell customers that they must make backups, coz sometimes it does hit the fan.

cheers,
John
