Write-Protecting a Cartridge
The tape drive uses standard and VolSafe cartridges. The VolSafe cartridge can 
be distinguished from the standard cartridge by its yellow markings.
Table 4-1 describes the write-protect switch positions.
To write-protect or write-enable a tape cartridge:
1. Hold the cartridge with the customer label side up and rear volser label 
toward you.
2. Locate the Write-protect switch on the right side of the cartridge.
3. Move the switch to the front of the cartridge (away from you) for the write-
protect position or toward you for the write-enable position.
