I’m looking for a simple, reversible way to disable disc writes in CD-R and DVD-R drives. I want to leave the drives physically in place and usable as read-only drives, but prohibit any kind of data writes to discs. It needs to be beyond the ken of general office workers, although tricky enough to elude the half-smart tech types would be good, too.
This would be under XPSP2 and Vista.
(Background: small company, about ten workstations, we deal in very sensitive information and it’s a policy not to have any writeable drives accessible to general users. Older CD-ROM and DVD-ROM drives are starting to fail, and as I’m sure everyone knows, it is getting harder and harder to find read-only drives… and they are often more expensive than full-featured writeable drives! So I’d like to be able to replace drives with whatever’s cheap that week, but be able to block disc writes. A simple setting somewhere, registry perhaps, that will do it?)
