[net.micro] Disk ][ write-protect mechanism problems

O05@psuvm.BITNET (09/03/85)

     Our Campus owns 25 Apple ][/+ and ][/e computers, and for reasons we won't
 go into now, the small arm which actually detects the write-pritect tabs exist
ance has broken off (worn out ... whatever) on about 1/3 of our drives.  After
consulting with our local Apple dealer, I find out that the small black plastic
 arm can not be independently replaced, but would require the replacement of th
e whole bottom of the disk drive (at $100 each !!!!!).
      IS THIS TRUE ???  If anyone out there knows if it is, or a quick solution
 to the problem, I'd appeciate the info.  It seems to me that you should be abl
e to jerry-rig the thing to work, but I'd rather like to have more opinions.
     
                                         Thanks in advance,

 Your users probably realized that breaking off the write-protect mechanism
allows them to write on both sides of a floppy disk without punching a hole
in the disk's other side (this has nothing to do with the original question,
 but it is most likely that the write-protect did not wear out.)

Couldn't you also just install a switch to enable/disable the write control
line? This would fix your problem without getting a new plastic gizmo.
