Does the drive spindle spin freely by hand?  It's possible that stiction is the issue.  If it's stuck, try forcing it to turn.  You've got nothing to lose because your stuck anyway.. literally.  

If it's not that than you either don't have power to the motor connected properly or your motor is gone, unfortunately.  

The other issue I've had with Widgets is the internal lens has come loose.  I had to open my drive and try to glue it back in place.  The drive was a write-off after that.
