Here's the short story.

Had to do a hard reboot of my computer because a game crash froze the screen.

When I rebooted, my 2gb Seagate Baracuda didn't detect. So I checked in BIOS. No mas.

I tried it in two other computers. Does not detect and doesn't seem to spin.

Wondering what's wrong with it and how salvageable is it? I'm willing to get a new board if it'll work as the board'll be cheaper than the drive.

If it doesn't spin, then it is most likely a PCB fault.

Check the TVS diodes and look for damaged chips.

A PCB swap plus firmware transfer should cost you US$50 or less.

TVS diodes?
