I think I always remembered to type PARK /H0 before shutting down my Coco  
system.  At least, I never had any real trouble with my two ST-225s and  B&B 
interface (one drive serves as backup and de-fragger for the  other).
 
I *have* had one drive refuse to spin up, once or twice.  As Gene (I  think 
it was Gene) suggested, a horizontal whack of the fist on a corner torques  it 
loose.
 
BTW, it gets harder and harder for me to remember that all you do to  
shutdown an OS9 system (Coco, MM/1) is to flip the switch!  Not recommended  with 
Doze or *IX.
