Figure 85. MODE Parameter Page Format
Each mode page contains a page code, a page length, and a set of mode parameters.
When using the MODE SENSE command, a Parameter Savable (PS) bit of one indicates that the mode
page can be saved by the drive in the reserved area of the drive. A PS bit of zero indicates that the sup-
ported parameters cannot be saved. When using the MODE SELECT command, the PS bit is reserved
(zero).
