Hi All,

I have a dead WD3200AAJS that does not spin up no noise at all. Thought it might be the PCB, took the PCB out and there is no visible damage at all.
Is there a way to measure voltage across certain points to see if it actually is the PCP? Since that drive has the bios on the main chip it is way beyond me to remove and re-solder it onto a working PCB. Any help is appreciated.

Use the search funtion for TVS, diode, etc. You should find plenty of info.

A damaged PCB doesn't necessarily need "visible damage" to not work.

I figured it can still be dead, due to time constrains i have, i bought a pcb, and sent in the drive for the IC swap, hopefully that will do it.
Thanks for the input guys.

I have the same problem with the hdd not spinning , but on the other had the pcb warms up when power is applied it is a WD3200BEVT-08A23T1.
Just wanting to know if I swap the pcb with a donor, would it work?

Thx

Rarely, most of the time it does not.
