Clicking for some drives/laptop drives especially.
IBM drives dying with the 'pixie dust' used on them usually get really loud and sound very high pitched.
Hmm.. freezer trick? You're really lucky if that worked, probably because the platters get smaller due to the coldness and re-levitates the head (it hovers very closely to the platter) .. Mostly only going to work on a head crash, and the only data your gonna get is where it didn't hammer onto the platter, AND if the head is still alive
