I can remember dropping a SCSI drive or two 4" to 6" onto the desk
to free it up so it would spin up again. (Drop so it lands flat on
its bottom, not sides or ends.) This was often necessary on drives
that had run non-stop for years, and were shut down long enough to
cool off. (Moving a computer room...) I believe there was a repair
spec describing this...
