Sounds like a faulty motor which is drawing too much current through the PCB and continually blowing your motor controller chip.

It might be a frozen spindle too. I have one that burned out the motor chip. When I replaced it, it immediately gets hot. Doesn't get hot when PCB is on another drive...

Hi,
R69 is located in the -5V DC-DC converter...
If R69 is damaged -> check Q3, U9, L7...
