Total number of user-addressable sectors
This field contains a value that is one greater than the total
number of user-addressable sectors. The maximum value
that shall be placed in this field is 0FFFFFFFh. The
0FFFFFFFh value applies to all capacities over 137Gbytes
(see Section 2.2 and 2.3 for related information).
