I was afraid of doing any damage so probably did not hit the case very
hard but so far hitting the metal casing with the handle of a

Another trick I saw way back when was to put the drive in a plastic zip-lock
bag and put it in the freezer for a day or two, then pull it out *in the bag*
and let it return to room temperature before removing the bag.
