Figure 72. M O D E Parameter Page Format
Each mode page contains a page code, a page length, and a set of mode parameters.
When using the M O D E SENSE command, a Parameter Savable (PS) bit of one indicates that the mode
page can be saved by the file in the reserved area of the file. A PS bit of zero indicates that the supported
parameters cannot be saved. When using the M O D E SELECT command, the PS bit is reserved (zero).
The file supports the following mode page code:

01 Read-Write Error Recovery Parameters
02 Disconnect/Reconnect Control Parameters

04 Rigid Disk Geometry Parameters
07 Verify Error Recovery Parameters

Figure 73. 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 M O D E SENSE command, the file will
terminate the command with CHECK CONDITION status.
