Appendix C. Mode pages
Mode pages are groups of parameters that the drive stores. These
parameters can be read using the Mode Sense command and changed
using the Mode Select command. These commands are described in
Sections 3.4.10 and 3.4.13. on pages 48 and 53.
This appendix contains the default parameters and the directly change-
able parameters for the mode pages. The current parameters and the
saved parameters are not shown.
Note.
The default values contained in this appendix may differ from the
default values actually contained in your drive. To determine the
default values, use the Mode Sense command.

For all mode pages:
• If the changeable value is 0, the initiator
cannot change the bit directly.
If the changeable value is 1, the initiator
can change the bit directly.
For example, in the mode page header, the changeable value for the
page code bits is 0, which means that the page code cannot be
changed; the changeable value of the PS bit is 1, which means that
the PS bit can be changed.
• During the Mode Sense command, the PS (parameter savable) bit
is 1, which means the mode page is saved on the disc. During the
Mode Select command, you must set the PS bit to 0.
• An “X” means that the value of the bit cannot be specified. For
example, the default value of bit 0 of byte 1 of page 00
H
(the Operating
page) cannot be specified because the bit can be either 1 or 0.
