Drive quit working. It appears that it no longer spins. I have tried thereset procedure, etc., & the drive lights up (AC Adapter ok). Drive shouldspin even w/o USB connection. Neither regular nor SuperDisks seem to spin. Noindication that motor tries to spin (no grinding or grunting, indicators don’tdim). I suspect some sort of interlock switch problem. What are thepreconditions to enable (or disable) the spin motor? I am comfortable withdetails & I troubleshoot for a living. I have a good DMM & o’scope and thecircuit board doesn’t scare me. I work with smaller & tighter circuitboards than this.
