So is the only solution to disallow user access to the device?
Operationally that is inconvenient in some cases, but every user
community has a few ill-intentioned people, and student groups may be
somewhat heavy on that. Security is more important than convenience, but
both are desirable.

We could go to burning all local reference data on CD-R instead of
CD-RW, have a separate CD-R drive, but as noted all of those are
undesirable drains on time and money. Clearly having some twit rewite
the CD-RW with their own information is even more undesirable, if that
wasn't clear ;-)
