Hi, i need an advice about my hard drive:

Seagate 7200.9
S/N: 3PM1FZ6A
ST3500641AS
P/N: 9BD148-304
Firmware: 3.AAJ
Datacode: 07084
Sitecode: AMK

I tried to mount this drive one day, my pc didn't power on.
So i tried in another pc and, omg, smoke!



So I read around forums by removing the burned protection diode the drive would be just ok to backup some data.
So I removed it, cleaned contacts and pcb and finally plugged again.

Result: no more "fireworks", but cycling (2sec more or less) "clicking" noise.

Do I need to find a new pcb (maybe controller fried?) or just mechanical parts dead?
What's your diagnosis?

There's something really wrong now. Maybe fried preamp INSIDE the drive HDA.
Need to diagnose it properly.
It was not a good idea to remove the TVS and leave the drive without any further protection.
If TVS have triggered, there should be a reason.

How do I diagnose that?

PS: The drive has broken because of damaged SATA molex that didn't fit 100% inside my seagate.
I think it caused a wrong alimentation or any voltage spikes that have burnt up the tvs.

Diagnose : by terminal then with PC3000.
THE PROBLEM IS NOT THE CAUSE BUT THE EFFECT.

How can I diagnose with pc3000? This is only enterprise stuff i think.

Is it probably simply the pcb controller f***ed up? Maybe weird voltages and stuff damaged the controller, not the mechanical parts such as heads.

Anyone have suggestions?

Yes it's enterprise stuff.

Probably preamp is dead.
which TVS was damaged? on the 5V or on the 12V line?
