These tape lengths are equivalent to consumer-grade video tapes. To ensure the

archivability of your data, Exabyte strongly recommends that you use EXATAPE

data cartridges for data storage.

As described in Appendix C, the CTS initially uses the settings of the CT and 112m

bits in the MODE SELECT command to size the 112m EXATAPE. The CTS

accurately resizes this tape as the tape position approaches LEOT. For this reason,

if the CT and 112m bits are incorrectly set, an 85h value may be returned for the

112m EXATAPE until the tape is resized.

Byte 02, Bit 7 - WP (Write Protect)

The Write Protect bit indicates if the data cartridge loaded in the CTS

is write protected. This bit is defined as follows:

0 – The data cartridge loaded in the CTS is not write protected.

1 – The data cartridge loaded in the CTS is write protected.
