If the drive doesn't spin, but does heat up, I'd guess that the spindle is somehow stuck. This would cause the motor to draw extra current, explaining the heat. I don't think that there is anything besides an RMA which would resurrect it. You might try pm'ing crashman (one of the tomshardware staffers - I seem to remember him saying that he used to work at a place which repaired drives.
As far as a used drive, the only one I have is a 250G caviar blue which was giving SMART errors last time I used it. Sorry
