I have a Western Digital 80 GB drive that has very important data on the drive. I have found a replacement PCB online for $49.99, but before I spend that money I want to be reasonably sure that is the problem. The drive is not spinning and does not show up in the WD diagnostics software.
Can anyone tell me what voltages I need to apply to the motor connectors to make it spin? I have checked the pins with power applied to the pcb and get nothing in any combination I test.
