I have successfully retrieved data from a dead scsi hdd by putting it in
the freezer for an hour, then quickly plug it in start PC mount drive
and dump/copy data to another disc.  It gave me about 10 minutes
operation before it started to give read errors again.  I think the idea
behind it is that there is enough toloerance in bearings etc when it's
very cold (shrunk) to operate, once things heat up and expand you get
into trouble again.  This is a common thing for data recovery places to
try first with problem drives.

HTH
