Hi guys,
I have a seagate ST3160812A that someone plugged the wrong power supply into ( it was in an enclosure and the enclosure was plugged into the wrong power supply ).

It will not spin. I believe there is a short in the PCB because when I install the drive in a desktop, the desktop will not start ( I believe it detected a short )

I'm going to try the PCB swap.
Found a drive with same:

firmware
site code
model
same RPM

I see others on here who mention config having to be the same and HDA P/N.

Where are those?
What do you guys think my chances are?

Thanks

Hello : alcon_s

Found a drive with same: model; FW version; config; number of PCB or same the electronic parts : IC controller; IC motor and swap the ROM

thanks

sigitharjono,
Hi,
Thanks for responding.
Where is the config? Isn't that a number on one of the chips?

Not sure how to match the IC controller.
Can you help me?

Thanks

This msg means that the motor is initialized or stuck after initialization after that head parks/unparks and drive reach ready state , In short if your pcb was working fine on the other hdd and on your drive gives this msg then most probably its a preamp problem .

i think, mostly the unit of head was not good! anyway thanks for you reply!
