Hard Drive Prevents Power Up

Either a short in a chip on the board, a short in one of the servos, or
both. Only the first can be fixed with a board swap.

Those symptoms suggest that the drive has a short circuit that is
drawing *way* too much current from one of its supply voltages.
Your system's power supply promptly shuts down when it senses the
overcurrent. Unless you find something obvious, such as a bent pin
on the power connector causing a short, you don't have much chance
of making the drive run again.

Exactly. In order to short out a PSU it takes in the 30-60A range
(depending on whether 5V or 12V is shortened out). That is enough
to melt connectors.

The drive is toast, unless it is a short very close to the power
connector, in which case removing the sort will help. Professional
data recovery may rescue your data.

Have you by chance used too long screws to mount the drive and
destroyed part of the PCB?
