     The IIc drive may just need to have its R/W head cleaned. Try using 
a Radio Shack 'Cleaner Disk' to clean the head on the IIc drive. You 
squirt some cleaner (iso. Alcohol) on the open patch of the Cleaner Disk 
and insert it patch-side-down into the drive and do a couple CATALOGs.

     If the disk from the IIe still does not boot, try other disks. 
Sometimes, a disk created/written-to on one drive will not work well on 
another due to differences in Speed and/or head alignment. If you can get 
some version of Copy II Plus to run on the IIc, select VERIFY and, then, 
SPEED and follow prompts to do a Speed check. If Speed is far from the 
correct value, adjust it.

     Bad head alignment-- i.e. bad enough to cause errors in reading 
commercial disks and others from a drive with a correctly aligned head-- 
is fairly rare. Steve Buggie <buggie@unm.edu> may have some ideas for 
checking and aligning the head in a IIc.
