I have a need for information about making a hard disk read only.

We have labs full of pc's and we would like to make it hard for students
to change the hard disk configuration.

I have had initial thoughts about writing a device driver/tsr that refuses
all write commands to the hard disk but I need to make the hard disk
unusable unless you boot from the hard drive.

Has anyone done this before and if so, any pointers on how to make the
disk unreadable unless you boot from the hard drive?

please reply via email
