WORM Cartridges
The Quantum DAT 320 tape drive includes support for both rewriteable
and Write-Once, Read-Many (WORM) data cartridges. WORM cartridges
provide for an enhanced level of data security against accidental or
malicious alteration of data on the tape cartridge. The WORM data
cartridge can be appended to maximize the full capacity of the tape
cartridge, but the user will be unable to erase or overwrite data on the
cartridge. Any attempt to modify a WORM cartridge to enable writing
over existing data will result in the media becoming permanently write-

the severity of the tampering, but no further appended backups will be
possible.
In order to use these cartridges, your backup software application needs
