OH.   another rusty old memory.  if you plugged a floppy cable in upside 
down (only possible if the cable wasn't keyed, but I remember quite a 
few that werent), it grounded both drive select and write select, and 
the drive would write nulls (or something) all over any track that was 
seeked to, without even sector formatting.   this would, of course, 
erase any disk you inserted.  also, the LED would stay on.
