Well, I thought I had explained it well enough the first time, but since you
request a better one...

     The drive, a 3.5 inch Central Point unit runs off of the UDC (Universal
Disk Controller: also CPS made) in my Apple IIGS.  Ever so often, rather
sporatically, I will turn on the GS in an attempt to get something useful  
(or maybe non-useful as the case may be) done.  When I turn the computer on,
the 3.5 drive will make a noise which sounds like (and is) the head moving back
and forth as the stepper motor seems to have a fit.  This continues  until I
either turn the computer off or hit reset.  When this *does* happen, I can not
boot up with any disk.  It happens when I turn on the computer whether or  not
a diskette is in the drive.  (obviously not related to a specific diskette).
The problem comes and goes of it's own accord.  Sometimes the drive works and
sometimes it doesn't.  Once turned on and running correctly, it seems to be
able to continue to work correctly.  I do not think the problem is the UDC
card because I plugged the drive into the back of my Apple 3.5 drive (daisy
chained it) to see what would happen.  This is not supposed to work normall,
but I thought I might see what it would do.  The moment power is supplied, 
the drive goes into a fit of stepper motor madness again.

    Any further questions?       - Nathan L. Lim (NuLL)
