3–6 AIT Drive Reference Guide
Operating the AIT Drive
Write-Protecting a Cassette
The cassette has a write-protect switch

to prevent accidental erasure of data. Before
loading the cassette into the drive, position the write-protect switch on the front of the
cassette. By moving the switch to SAFE, the cassette is write-protected and by moving
the switch to REC, the cassette is write-enabled.

NOTE: Your tape switch may differ from the illustration.
Certain AIT cassettes provided by Compaq support Memory in Cassette (MIC). This
feature enables the cassettes to store important cassette information in memory, which
allows faster access to data. MIC cassettes can be easily identified by the gold
connector pads located left of the write-protect switch.
IMPORTANT: The Tape Log, which contains a history of usage of the tape, is not updated
when the cassette is write-protected. The Tape Log becomes inaccurate if a cassette is used
write-protected, and the media warning cannot be relied on to indicate that the cassette needs
to be copied and replaced.
Using your fingernail, push the switch in
the direction of the arrow to protect the
tape from writing or accidental erasure.
Return the switch to its original position to
re-enable writing.
