APPENDIX A: SDLT I Tape Cartridge
When a tape cartridge is loaded in the drive and the tape cartridge’s write-protect
switch is moved to its write-protected position (to the left as you face the label/
switch side of the tape cartridge), the drive turns on its write-protect indicator LED
immediately. If the drive is currently writing to the tape, the write-protect feature
does not take effect until after the current WRITE operation completes.
