From NY Times article here: Text I haven't tried it myself, but may be a last resort technique.
"Crashed Hard Drive
If ? no, make that when ? your PC?s hard drive crashes and can?t be read, don?t be too quick to throw it out. Stick it in the freezer overnight.
?The trick is a real and proven, albeit last resort, recovery technique for some kinds of otherwise-fatal hard-drive problems,? writes Fred Langa on his Windows Secrets Web site. Many hard drive failures are caused by worn parts that no longer align properly, making it impossible to read data from the drive. Lowering the drive?s temperature causes its metal and plastic internals to contract ever so slightly. Taking the drive out of the freezer, and returning it to room temperature can cause those parts to expand again.
That may help free up binding parts, Mr. Langa explains, or at least let a failing electrical component remain within specs long enough for you to recover your essential data. "
