No choice, that is, other than running a SHARE replacement program
such as NOSHARE.COM (see below).  This program takes over handling of
of FCB disk I/O, and simply causes all attempts to use FCBs for disk I/O
to fail, with appropriate error/result/status codes.  Since practically
nobody needs FCB calls to work, this is a dandy solution, and it prevents
anything using FCBs from damaging the file structures, including DOS itself.

begin 644 noshare.com

end

As you can see, NOSHARE.COM is much much smaller than SHARE,
and can be loaded easily from your AUTOEXEC.BAT file.  

But be sure to remove SHARE.EXE from the root directory and also
from the directory holding COMMAND.COM (unless you use 4DOS instead),
to prevent DOS from automatically finding and loading it also (waste of mem).
You'll know you've done it right as long as you are still getting the
WARNING: SHARE MUST BE LOADED FOR LARGE MEDIA messages (or whatever they say).
