I just park it in the freezer with the cables out to the computer and start working as soon as it
gets cold. You can get a whole day that way and recover virtually all of the data.

How's that for a big [well, clumsily oversized], power-cooled external case?

I was thinking of mentioning the baggie but I eventually stopped doing that because I don't
leave the drive 'on ice' for long before turning the attached computer back on. It cools quicker
without a baggie so it tends to take only about twenty minutes before SpinRite can start
recovering the few lost sectors if any were damaged.

Afterwards they can become an interesting bit of artwork or even a cute [if noisy] desk fan if
the platter bearing is still good enough for that.
