That should have a normal IDE 80GB drive in it. Look at some 30 buck drive enclosure from http://www.google.com/search?hl=en&q=USB+DRIVE+ENCLOSURES&btnG=Google+Search&aq=f&oq= and move the drive into its new home.
I have misplaced the power cord to this unit. Can someone PLEASE email me if they know where I can find a replacement??? Got to get back into this external drive.
