[comp.sources.wanted] Hard Drive protection program wanted

pdp111@phakt.usc.edu (PDP-111 Instructor) (03/25/90)

We own a lab which contains 45 stand-alone IBM PC compatible 286/386
machines.  Each of them has a 30M hard drive with all the application
softwares on it.

In order to protect the hard drives from being written on by hundreds
of daily users, currently, we install a protection program which will
automatically reboot the system anytime there is an attempt to write to
the drive.

There are two problems:
1.  Some students might lose all their work by accidentally trying to save
   work on hard drive.  Also, some of the application packages we have 
   generate temporary files on hard drive while exiting, which will cause 
   the reboot.  Pipe cannot be run on C drive either since it generates 
   temporary files.

2.  The protection program is loaded during the execution of autoexec.bat.
   It can, thus, be bypassed by hitting ^C or break key.

Is there any better program available ?
