* Replies to READ_FORMAT_CAPACITIES look like this:
*
* struct format_capacity_list_header
* struct format_capacity_descriptor[1..n]
*
* These are similar, but not totally identical to, the
* defect list used to format a rigid disk.
*
* The appropriate csio_decode() format string looks like this:
* "{} *i3 {Len} i1 {Blocks} i4 {} *b6 {Code} b2 {Blocklen} i3"
*
* If the capacity_list_length is greater than
* sizeof(struct format_capacity_descriptor), then there are
* additional format capacity descriptors available which
* denote which format(s) the drive can handle.
