v Before you apply a new label, remove the old label by slowly pulling it at a right angle to the cartridge case. v Use peel-clean labels that do not leave a residue after being removed. If there is glue residue on the cartridge, remove it by gently rubbing it with your finger. Do not use a sharp object, water, or a chemical to clean the label area. v Examine the label before applying it to the cartridge. Do not use the label if it has voids or smears in the printed characters or bar code (a library's inventory operation will take much longer if the bar code label is not readable). v Remove the label from the label sheet carefully. Do not stretch the label or cause the edges to curl. v Position the label within the recessed label area ( 5 in Figure 9 on page 33). v With light finger pressure, smooth the label so that no wrinkles or bubbles exist on its surface. v Verify that the label is smooth and parallel, and has no roll-up or roll-over. The label must be flat to within 0.5 mm (0.02 in.) over the length of the label and have no folds, missing pieces, or smudges. v Do not place other machine-readable labels on other surfaces of the cartridge. They may interfere with the ability of the drive to load the cartridge. Write-Protect Switch The position of the write-protect switch on the tape cartridge ( 1 in Figure 10) determines whether you can write to the tape. If the switch is set to the: v The locked position (solid red), data cannot be written to the tape. v The unlocked position (black void), data can be written to the tape. If possible, use your server's application software to write-protect your cartridges (rather than manually setting the write-protect switch). This allows the server's software to identify a cartridge that no longer contains current data and is eligible to become a scratch (blank) data cartridge. Do not write-protect scratch (blank) cartridges; the tape drive will not be able to write new data to them. If you must manually set the write-protect switch, slide it left or right to the desired position. 1 Figure 10. Setting the write-protect switch 34 IBM 400/800GB LTO3 Tape Drive User's Guide A67E0026
