I am trying to work out if my HDD is dead from a motor failure or PCB failure. there is no observable damage on the PCB. It failed while i was access data.
When i connect to a powered SATA USB, the usual spinning up doesn't happen and there is some buzzing sounds, repeated 3-4 times before nothing happens.
What i am trying to work out, is the motor dead or spindal seized, or is the PCB not giving the right power.
I have measured the voltage on the motor connectors on a healthy drive while spinning at normal RPM, its either at 3 or 6v depending on connector.
On the suspect drive while its trying to spin up and buzzes the voltage varies, but the voltages never get over 1.5v.
This seems to me to indicate that the PCB is faulty and not giving the motor enough voltage to get turning.
Is there any other way to diagnose if its the PCB or the motor, any locations i can measure voltage on the PCB to confirm its health?
