DLT/SDLT Visual Media
Inspection Guide

Ideally you should inspect the cartridge each time a tape is loaded or changed.

When a tape cartridge is dropped or subject to a hard physical shock.

When a shipment of tapes shows any sign of shipping damage.

If the DLT, DLT VS or SDLT drive becomes inoperable after loading a tape.

If a drive error occurs, inspect the current and previous cartridge used in that drive before using the drive or media again.

Inspect the case for cracks, chips or signs of damage.

Inspect the exterior of the cartridge for chips, cracks, dents, or missing screws. Gently shake the cartridge. Listen for rattling or loose pieces

Ensure that the cartridge door is moveable and that the spring is present.

Move the write protect switch. It should snap into write-protected mode and write-enabled mode.

Open the cartridge door and gently inspect the cartridge leader to verify that it has not been damaged and is in the correct position.
-DLT cartridges: Check the height of the leader to ensure that the loop is sticking up approx. 3/16" or 4mm.
-Super DLT Cartridges: The buckle should not be bent in or out.

Check that both reel locks are visible. Verify operation using a small flat blade screwdriver. The reel locks should spring back when released.

Confirm the spring-loaded hub on the bottom of the cartridge is centred. Press the hub, it will spring back if operating properly.
