Parameters Savable. This bit is only used with the MODE SENSE com-
mand. The returned value of 0 indicates that the target is not capable
of saving this page in a non-volatile vendor specific location
reserved with the MODE SELECT command.
Notched (banded) Drive. A value of 0 indicates that the drive is not
notched and that all other parameters in this page are returned as 0.
The default value of 1 indicates that the device is notched. For each
supported active notch value, this page defines the starting and ending
boundaries of the notch.
Logical or Physical Notch. The default value of 0 indicates that the
boundaries of the notch are based on the physical parameters of the
logical unit. The cylinder is considered most significant and the head
least significant.
A value of 1 indicates that the notch boundaries are based on logical
blocks of the logical unit.
This field indicates the maximum number of notches supported by the
logical unit. The value cannot be changed.
The Active Notch field indicates the notch referenced by this, and sub-
sequent MODE SELECT and MODE SENSE commands. The value in
this field can be changed by a later MODE SELECT command. The val-
ue of the active notch must be = 0 and = 24. An active notch of 0
indicates that this and subsequent MODE SELECT and MODE SENSE
commands refer to the parameters that apply across all notches.
This field indicates the beginning of the active notch or, if the active
notch is 0, the beginning boundary of the logical unit. If the LPN value
is 1, the starting boundary is a Logical Block Address.
If the LPN value is 0, the three most significant bytes designate the
starting cylinder number and the least significant byte is the starting
head number. This field is unchangeable. When used with the MODE
SELECT command, this field is ignored.
792DH = 31021 which refers to the ending cylinder, 01H is the end-
ing head number
792DH = 31021 which refers to the ending cylinder, 03H is the end-
ing head number
792DH = 31021 which refers to the ending cylinder, 07H is the end-
ing head number
This is a 64-bit bitmap that indicates which MODE command pages
contain parameters that may be different for different notches. The
most significant bit (MSB) corresponds to Page 3Fh (Vendor-Unique
Caching Page), and the least significant bit (LSB) corresponds to Page
00h
(Unit Attention Control Page).
If a bit is 1, the corresponding mode page contains parameters that
may be different for different notches.
If a bit is 0, the corresponding mode page contains parameters that are
constant for all notches.
The value of 1 in bits 3 and 12 indicates that Page 03h and 0Ch contain
different parameters for different notches.
