Write Protection

To prevent accidental erasure of your data, each media cartridge has a write-protect

switch. When active, this switch prevents data from being written to the cartridge.

To enable write-protection, move the switch on the front of the cartridge down, so that

the small orange rectangle appears.

To disable write-protection, move the switch up so that the orange rectangle is not

visible.

When a write-protected cartridge is inserted into the drive, the yellow Write Protect

LED on the panel lights. Set as new head.

The Load/Unload menu enables the operator to specify a source and a destination for a

cartridge movement. As a result, the procedure to load is the same for unloading. To

load or unload a tape from the front panel of the module, use the Load/Unload menus as

shown in Figure 6-21

Note that DLT1 has a tape loaded. When this screen indicates DLT1 Idle, the drive has a

cartridge loaded and is awaiting instructions. Note also that Slot 1 of the magazine has a

cartridge present, while the remaining slots are empty.

From the Default screen, enter the Menu mode by pressing Enter. The Main menu

shown in Figure 6-22

is next to the message “Load/Unload.” Press Enter to display the first

Load/Unload submenu, shown in Figure 6-23.

Caution. For valuable data, always make sure that the cartridge is write-protected before

inserting it into the drive.
