REQUEST Sense Key set.

Partition Size Descriptor
Partition size in megabytes, in binary notation. Bytes 8, 9: Partition Size Descriptor. For a Mode Sense Command,
the value in this field is invalid unless the Mode Sense Command follows a successful Mode Select Command Page

be set to the default value of 00 00. There is no relation between this field and the IDP bit in the parameter block of
Mode Select Page 11h.
