APPENDIX A: Super DLTtape I Data Cartridge SDLT 220 and SDLT 320 Product Manual

A-8 March 2004 81-85002-01

• Move the write-protect switch to the left to enable write protection (existing

data on the tape cannot be overwritten, nor can additional data be appended to

the media).

• When the write-protect switch is moved to the left, a small orange rectangle is

visible. This is your visual reminder that data cannot be written to the tape.

• Move the write-protect switch to the right to disable write protection (existing

data on the tape can be overwritten, and additional data can be appended to the

media unless the cartridge is write-protected via firmware). When write-

protection is disabled, no orange rectangle is visible.

When a data cartridge is loaded in the drive and the data cartridge’s write-protect

switch is in its write-protected position (refer to Figure A-6), an SDLT 220 drive

turns on its write-protect indicator LED immediately (on the other hand, an SDLT

320 does not illuminate any front panel LED, because that LED has been assigned

to a different drive feature; refer to Table 5-2 on page 5-10 for more details). If the

drive is currently writing to the tape, the write-protect feature does not take effect

until after the current WRITE operation completes. For more details, refer to Table

A-1 on page A-8.
