So, umm, when it worked why didn't you get the data off and
have no need to try again? That's the most important part,
having a system and spare space available so after you pull
it from the freezer it is time to immediate salvage what
data you can.
Try this:
Take a hairdryer, or turn on the oven then off again and let
it cool down to about 75C. Put the drive in oven for 10
minutes, remove and garnish with parsley. Just kidding
about the last part. Oven or point hairdryer at motor
bearing and bottom where arm bearing mounts, heating to
hopefully make the lubricant flow around a bit.
Next, let it cool to room temp then put in a baggie you
sqeeze the air out of and seal. Put in freezer till it's
just above freezing, remove and let warm up just a tiny bit.
Before opening bag, have masking tape ready. Quickly open
bag, plug in data cable and power cable. Close bag as much
as you can (thinking a ziplock type bag seal) and use the
masking tape to seal it the rest of the way so air can't get
in. This keeps moisture from condensating on it. If you
are not quick enough and see moisture you will have to start
over and make sure room air doesn't get to it very long
while it's so cold.
