Maximum LBA Address
Words 4 - 7 define the maximum LBA address. This is the
highest address accepted by the device in the factory default
condition. If no DEVICE CONFIGURATION SET command
has been executed modifying the factory default condition,
this is the same value as that returned by a READ NATIVE
MAX ADDRESS command.
