   I've no direct knowledge, but would think that the heating/cooling   
   cycles a deep space probe might encounter would be rather difficult on   
   a disc drive.  It is a rather delicate component - certainly compared   
   with say magtape and definitely so compared to core :) I would hazzard   
   a guess that a disc drive requires environmental conditions not too   
   far from those desired/required by humans.
