However, he explained that the read would need to be completed by the time the drive thaws out and before the moisture inside condenses.  Considering it's 250 gb, I'm inclined to think that it would thaw faster than it could be fully read.  HOWEVER, I would consider that as an option of last resort.

I have to disagree David I think the moving parts are what almost always 
fails the drive by wear or a slight defect causing a slight wobble to 
happen and when you consider those disk are whirling around a fixed 
center and the arm of the RW head has a different center and has to move 
the full length of the arm travel holding a tolerance less than a cig 
paper thick .... Sam thinks that way too because that is the purpose of 
putting the drive at a diff angle letting gravity and force work from a 
different direction. I think its a bloody miracle of engineering to get 
it to work at all.

David I am watching this episode very closely and i truly think you are 
in good hands. You also have more patience than I and I sure hope it 
pays off for you.
