Probably true.  I hesitate to suggest this, but sticking the drive in a
freezer (preferrably in a ziplock bag) for a few hours or overnight
might help.  Stories from people claiming "I swear it works!" go back
years.  

To the exent it does work, it might give Kelly enough time to attempt
recovery.  If more time is required, he can try and find a creative
workaround for the 5 meter max length for USB cables.  Also,
experimenting with dry ice or acetone baths might prove to be
interesting, or at least educational. ;-)
