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 32):
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.
With the write-protect switch in either position, data can be read from the
cartridge.
