SO, I somehow wedged a drive fan power adapter in the end of my drive upside-down. Even though it is keyed specifically to prevent that. I know, I know. it is a horrible thing. So I basically had 12v on the 5v rail and 5v on the 12v rail. And now the drive will not spin up when powered normally. I’ve pulled off the logic board and there is no sign of charring or burning near the two diodes next to the voice coil contacts. I tried to test them at 200ohm on the volt meter but im just getting a 1 when testing both directions, on both diodes. So i can’t really tell if these were blown or not. I have a spare drive that I can swap parts from if needed, but now im not sure if the over voltage did something worse then just blew out the TVS.
Also here are the specs for the drive
