There are things that can be tried, Zack. Sometimes you get clues as to the problem. If the drive isn’t detected by the BIOS or it is making odd repeating noises, like clicks or whirs, it might be not be spinning up. I would bonk the drive on the desk or floor a couple of times, then reconnect and hope for the best. And I did once get a drive to the point where it could be accessed for a little while by leaving it in the freezer overnight. About my last resort would be to swap the electronic controller card on the bottom with another of the same type, in case the problem was not the drive itself.
