The cassette also provides for write protection so that existing data on the cassette is not overwritten. A
write-protected cassette allows the existing data to be read but does not allow new data
to
be written
to
the
tape.
NOTE: A write-protected cassette does not allow the error log (in the System Area) to be
updated.
Figure 8-9 shows the sliding write-protect tab on the DAT cassette and its positions for write protect and
