Any suggestions on a way to revive it? I've tried the freezer trick with no luck (it just makes it louder). I'm almost tempted to heat it and see what happens, but I'll wait on that for now at least - I'm just sort of running out of ideas.
It's a Barracuda ATA V, 120gb, with the 3.33 firmware. The first three characters of the serial number are 3KA, which I'm told is important. If you have one of those I'd happily buy it off you so I could try an electronics swap.
