I guess this isn't likely to work now that the drive's been opened, but I've
had surprisingly good luck with dead drives by putting them into a static
bag, sealed up with tape, and leaving them in the freezer overnight! This
has worked for 2 out of 3 drives I've tried it on, whether it was just
coincidence or dumb luck (or combinations of the two!). Anyway, when
there's nothing to lose, you get all kinds interesting thoughts on how to
revive that drive one last time
