Figure 3-6. Setting the Write-Protect Switch 1 Write-Protect Switch To set the switch, slide it left or right to the desired position. Notice: Always set the write protection tab prior to loading the cartridge into the drive. Sliding the tab after loading will cause unpredictable results and could result in drive errors or backup failure. Caring for Tape Cartridges Notice: Do not insert a damaged tape cartridge into your tape drive.
v Never ship a cartridge in a commercial shipping envelope. Always place it in a box or package. v If you ship the cartridge in a cardboard box or a box of a sturdy material, ensure the following: – Place the cartridge in polyethylene plastic wrap or bags to protect it from dust, moisture, and other contaminants. – Pack the cartridge snugly; do not allow it to move around. – Double-box the cartridge (place it inside a box, then place that box inside the shipping box) and add padding between the two boxes.
Handle the Cartridge Carefully v Do not drop the cartridge. If the cartridge drops, slide the cartridge door back and ensure that the leader pin is properly seated in the pin-retaining spring clips. v Do not handle tape that is outside the cartridge. Handling the tape can damage the tape's surface or edges, which may interfere with read or write reliability. Pulling on tape that is outside the cartridge can damage the tape and the brake mechanism in the cartridge. v Do not stack more than six cartridges.
