WORM Cartridges

4

The Quantum DAT 160 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-

protected. It should still be readable in a WORM drive, depending upon 

the severity of the tampering, but no further appended backups will be 

possible.
DAT 160 WORM data cartridges are clearly identified by their distinctive, 

two-tone cartridge color. They do not have a write-protect slider. In order 

to use these cartridges, your backup software application needs to 

support DAT 160 WORM cartridges. Please check with your software 

vendor to be sure.
