Write-Protecting Ultrium Cartridges
Each cartridge has a sliding write-protect switch. Using the write-protect
switch ensures data safety for files that have been previously written to
tape, preventing additional files from being written to that tape.
To change the write-protect setting, slide the red tab on the base of the
cartridge (Figure D-8 on page D-22):
• Right to prevent data from being written to the cartridge. The red tab
on the cartridge displays a padlock when the write-protect switch is
in the “ON” position.
• Left to allow data to be written to the cartridge (unless the tape is
write-protected electronically through your backup software). The
padlock on the red tab cannot be seen and the hole is exposed when
the write-protect switch is in the “OFF” position.
NOTE With the write-protect switch in either position, data can be read from the
cartridge.
