	Jim;

	`If this is a Double Sided drive, try turning the drive Upside down.

	Yup, thats right. Sounds like a few drives that I looked at,that had 
	the same symptons, and while working on the drivem I turned the 
	Mech upside down, and it worked fine. Place it back rightside up, and
	bang, same problem. 

	Seems that the problem is that the Direct drive motor either has 
	shorted windings, or a controllinf chip of the PCB that it's mounted
	to has problems. In any case, I have both the drives sent into 
	Atari, and had replacements back in Two weeks!

	Never really looked into the drive too far to get the exact cause 
	as the owners were in a hurry to get the drive back and working, and
	seeing that I don't have a full parts inventory, it was done this way.
	No One regretted this. I believe that the cost was in the 
	$80~90 range.

	Who knows, one day I might get another to work with a little longer
	and decipher what is the exact cause.
