You might try cleaning the drive,if the head is severely soiled 
it may not read anything. Have you tried running the self test
(while holding down the 2 apple keys & control, press & release 
the reset key)?

The 3.5 unidisk won't work on the earlier IIc unless it's had 
a ROM upgrade(the IIc that is). The Laser 3.5 isn't compatible 
with any Apple II unless it has a special controller card, 
which of course a IIc doesn't. The Laser 3.5 is actually a 
Macintosh drive with the addition of an eject button.
