Problems! Disk ][ drive just whirs and whirs; IIc monitor knob stuck; IIe enhanced not...

Lucked into some old Apple II equipment.  Had a couple of hardware 
questions.
  
1)  The Disk ][ drives simply whir and whir but do not read diskettes.  

I got a copy of Copy II Plus and, starting up with an Apple 5.25" drive, 
checked the speed of one of the Disk ][ drives, which was right in 
specs. Tried formatting some disks in ProDOS, but the whirring goes on 
and on.  Then tried DOS 3.3 and it was seeming to work until I got an 
I/O error with a statement about Track $11 and Sector $F.  Got the same 
message when trying to format a second diskette.  


2)  Apple IIc 9" green text monitor.  The contrast knob on the side is 
stuck.  Any suggestions of how to unstick it?


3)  One of the computers is an Apple //e, with the enhanced sticker on 
the keyboard light.  Yet when it boots up, the screen displays Apple ][ 
not IIe. There is an 80 column card in that unit, but not an extended 
memory one.   What's going on?


I have a lot of drives, controllers, a RamWorks II memory card, and IIes 
in this cache, so if there's some combination of things to try, suggest 
away!
