 If this is a Seagate drive mech, there were problems on some of their drives
with stiction (the tendency of two smooth surfaces to stick together), in
combination with a lack of torque in the drive motor. A friend of mine had 
this happen to his drive in a PC. He would get it to start by picking up the
case and spinning it slightly along the axis of the drive motor (which would 
break the stiction bond between the head and the platter). It doesn't take
much of a twist to break the head loose (20-40 degrees). Do you park the 
heads on your drive when you shut it down?
