Can a CD-R drive force a second pass burning over existing data to make the disc unusable? Perhaps with drive firmware modification.

Afaik you can "erase" contents of a disk with open session. Data is still there just invisible without specialized tools, enough to fool non nerds.
It would be safer to use a read-only drive when reading back the backups.
