Apple IIgs not recognizing 3.5 drives

[obsbedia2@aol.com (Obsbedia2)]

this is weird...
	two Apple IIgs computers at school suddenly stopped recognizing their 3.5
drives.  It was as if no power was making it to the drive, even to eject a
disk.  I tried other 3.5s, but the same thing occured.
	today, I tried new computers--same thing,
	then I tried new drives--some worked and some didn't--but the ones that didn't
later did
	satisfied with any working set up, I was ready to pack it up when suddenly the
3.5 drives weren't being recognized again.

	I've checked the control panel and set SLOTS to SCAN or DRIVE 6 or DRIVE 5. 
5.25 inch drives always work.

	Again, except for the monitors, keyboards, mice and cords, these are unrelated
components.  Slot 5 is never set to MY CARD and none of the units seem to be
set up for a network.  In fact, the original two  //gs computers were working
fine for about 5 months.

	Any ideas on what to do next?  These computers are working fine with 5.25
drives.
