An ex-colleague of mine used to work at Quantum (HD manufacturer, acquired by Maxtor, then Maxtor got bought by Seagate) said that the majority of problems seen in RMAed (sent back for warranty) drives was circuit-board related and not mechanical. All the technicians had to do was replace the circuit board.
Hopefully you've only got a bad circuit board and not bad mechanical parts.
