Parameters Savable. A bit of 1 indicates that the tape drive can save the page in
nonvolatile memory. If the PS bit is 0, the tape drive cannot save the supported
parameters. (The tape drive does not support Savable pages.)

This field indicates the number of bytes in that page. However, the value does not
include bytes 0 and 1. The tape drive returns the length on MODE SENSE and
must subsequently set it to the same value when performing MODE SELECT.
