**
** If the SCSI device doesn't support changing its capacity by changing
** the NUMBER OF BLOCKS field using the MODE SELECT command, the value
** in the NUMBER OF BLOCKS field is ignored. If the device supports changing
** its capacity by changing the NUMBER OF BLOCKS field, then the
** NUMBER OF BLOCKS field is interpreted as follows:
** a) If the number of blocks is set to zero, the device shall retain
** its current capacity if the block size has not changed. If the
** number of blocks is set to zero and the block size has changed,
** the device shall be set to its maximum capacity when the new
** block size takes effect;
**
** b) If the number of blocks is greater than zero and less than or
** equal to its maximum capacity, the device shall be set to that
** number of blocks. If the block size has not changed, the device
** shall not become format corrupted. This capacity setting shall be
** retained through power cycles, hard resets, logical unit resets,
** and I_T nexus losses;
**
** c) If the number of blocks field is set to a value greater than the
** maximum capacity of the device and less than FFFF FFFFh, then the
** command is terminated with a CHECK CONDITION status. The sense key
** is set to ILLEGAL REQUEST. The device shall retain its previous
** block descriptor settings; or
**
** d) If the number of blocks is set to FFFF FFFFh, the device shall be
** set to its maximum capacity. If the block size has not changed,
** the device shall not become format corrupted. This capacity setting
** shall be retained through power cycles, hard resets, logical unit
** resets, and I_T nexus losses.
