Table 5.50 Logical Unit Control Page - Hitachi Ultrastar 15K73 Reference Manual

When the LPN bit is set to 0, the boundaries indicate physical parameter.
When the LPN bit is set to 1, the boundaries indicate logical block address.
Since the controller supports only the Cylinder & Head number format, LPN bit
should be set to 0
The Maximum Number of Notched field indicates the number of notches
supported by the drive.
The Active Notch field indicates the notch(1 through n, n: number of notches)
referred to by the current and subsequent MODE SELECT / MODE SENSE
command. When this field is zero, the parameters of current and subsequent
MODE SELECT/ MODE SENSE command is applied across all notches.
The Starting Boundary field indicates the beginning of the notch specified in the
Active Notch field. The three most significant bytes of this field represent the
cylinder number and the least significant bytes represent the head number.
The Ending Boundary field indicates the ending of the notch specified in the Active
Notch field. The three most significant bytes of this field represent the cylinder
number and the least significant byte represents the head number.
The values of the Starting Boundary and the Ending Boundary field specified by
the MODE SELECT command are ignored.
The Pages Notched field contains the bit map information of mode pages of which
parameters may be different for different notches. The most significant bit of this
field corresponds to mode page code (3F)
corresponds to mode page code (00)
