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).
The drive supports the following mode page code:

Figure 86. Page Code Usage
The page length field specifies the length in bytes of the mode parameters that follow. If the initiator does
not set this value to the value that is returned for the page by the MODE SENSE command, the drive will
terminate the command with CHECK CONDITION status.
