PS Bit
A Parameters Savable (PS) bit of one indicates that the page can be saved in nonvolatile
memory by the drive. If the PS bit is zero, the supported parameters cannot be saved.
(Saveable pages are not supported.)
Additional Page Length
This indicates the number of bytes in that page. However, the value does not include
bytes 0 and 1. The length is returned on MODE SENSE and must subsequently be set
to the same value when performing MODE SELECT.
