I teach a class for which we have a single stand-alone NeXT running
OS 2.1. Security in the room with the NeXT is handled through a key
sign-out procedure. Otherwise the students are unsupervised. Because
of disk space limitations, I would like to have an optical disc mounted
at all times. But because of the size, portability, and (now) expense
of the optical discs, I am afraid that a student could easily walk out
with it. So:

Is there any way to prevent disc ejection for users without root access?
Preferably, I would like to prevent it both from the Workspace menu as
well as the Terminal. If not, is there something that can be done to
physically prevent the disc from ejecting? Thanks for your help.
