The hard drive does not work after incorrect power supply, what is the reason?

Question

Electronics

The hard drive WD 500 gb black, after an accidental incorrect power supply (when the PC was on, I wanted to connect a sata drive and accidentally touched the wrong side on the adapter for 1 second), the PC rebooted, plus the hard drive does not even make a sound of rotation, the diodes have already been ringing and soldered it still does not work, plus within 8 seconds the krutilka (vcm controller) heats up quite well, what could be the breakdown? it doesn’t look burnt anywhere, although during the whole event, when it closed, it smelled a little burnt near the power
connector at the bottom of the board example

Answer 1

Check protective diodes (suppressors) first, not capacitors. What happens now with proper nutrition, the block goes into defense?

Answer 2

I had something similar in repair, I’ll say for sure it’s impossible to reanimate 100%, the controller burned out, donors shouldn’t exist in nature, because they come with their own individual calibrations for each disk.
All advice (answers) is just a hopeless attempt to restore a particular corpse.
No need to suffer, all the possible elements have rung for a state of good condition and throw the disk into the trash.
IMHO!

Answer 3

Check the capacitors on the hard drive board, throw out the broken ones. Change the controller, most likely it was broken by reverse voltage.

Answer 4

I advise you to ring the motor, possibly a short circuit.
In theory, it should be from 1.5 to 3 ohms.
