Table 14-21:
The Partition Size Unit of Measure (PSUM) field is only
valid when the IDP bit is set. If the IDP bit is not set
this field is ignored.
unit of the Partition Size Descriptors is MBytes and a
value of 3 indicates that the unit of the Partition Size
Descriptors is GBytes. The maximum value of a Partition
Size Descriptors field is 65535 (FFFFh).
that the maximum partition size when using PSUM equal to
2 is 65535 Mbytes. Partition sizes greater than 65535
Mbytes must be set by using PSUM equal to 3 and use
GBytes as unit in the Partition Size Descriptors.
When the currently mounted volume has a total capacity
of 65535 MBytes or less MODE SENSE will always set this
field to 2 indicating
Descriptors unit is MBytes.
above 65535 MBytes MODE SENSE will always set this field
to 3 indicating that the Partition Size Descriptors unit
is GBytes.
The Partition on Format field must be set to 0, it is
not changeable.

This field must be set to 01h, it is not changeable.
This indicates that the Drive is able to independently
recognize the format on the medium.
The Partition Unit field must be set to 9 when the PSUM
field is set to 3.

Resulting Action
The medium is partitioned into a single partition
covering the whole medium.
The medium is partitioned according to the supplied
Additional Partitions Defined field and the Partition
Size Descriptors.
