I hadn't thought of that. Question: do you get a different directory 
output listing when you change the dir to dir1?  Or do you get a disk 
error because both drives are trying to drive data up the cable, which 
won't fly too well for obvious reasons.

Some 5.25 drives, most in fact, had a jumper that could cause them to take 
the DS line to activate the led, and if on the other set of pins the led 
is tied to the motor on input.  The artwork on the pcb for the older drive 
would have an M# label where the # could be an s or an o, maybe an e even.  
The 3.5 is likely hard wired but might have a cut & solder bridge place on 
the pcb if you get out a strong enough magnifying glass.
