Inspecting DLT Cartridges
NOTE Make it a practice to visually inspect your tape cartridges when removing 
or loading them into your tape library or autoloader. Taking a few 
minutes to check the condition of the cartridges will lower the risk of 
repeated failures and help ensure uninterrupted backup. 
Repeated drive failures may indicate defective tapes. Tapes need to be 
inspected and replaced if they have been dropped, damaged, or used with 
a failed drive. To determine if the tapes have been damaged:
• Gently shake the tape cartridge to verify that no internal parts are 
rattling.
• Visually inspect the tape for a broken, unseated, or misaligned tape 
leader (item A in Figure 2-1 on page 2-7). 
To check the leader position:
1. Press in the door lock (item C in Figure 2-1) to release the 
cartridge door.
2. While pressing in the door lock, push the tab down to open the 
door. Be careful not to touch the tape after opening the door.
• Verify that the spring-loaded hub (item B in Figure 2-1 on page 2-7) is 
centered within the circular opening on the bottom of the tape 
cartridge. Gently press the hub and make sure that it springs back 
into place.
