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
32. Therefore, on power-up without a Mode Select Page 32h, the Current Page 32h Partition Size Descriptor should
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.
