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 ?
