Hitachi HDS721050CLA362 Specifications page 200

Device returns command aborted for a second non-volatile Set Max Address command until next power on or
hardware reset.
Device returns command aborted during Set Max Locked mode or Set Max Frozen mode.
After a successful command completion, Identify Device response words (61:60) shall reflect the maximum
address set with this command.
If the 48-bit Address feature set is supported, the value placed in Identify Device response words (103:100) shall
be the same as the value placed in words (61:60). However, if the device contains greater than 268,435,455
sectors, the capacity addressable with 28-bit commands, and the address requested is 268,435,455, the max
address shall be changed to the native maximum address, the value placed in words (61:60) shall be
268,435,455 and the value placed in words (103:100) shall be the native maximum address.
If a host protected area has been established by a Set Max Address Ext command, the device shall return
command aborted.

Option bit for selection whether nonvolatile or volatile. B=0 is volatile condition. When
B=1, MAX Address which is set by Set Max Address command is preserved by POR.
When B=0, MAX Address which is set by Set Max Address command will be lost by
POR. B=1 is not valid when the device is in Address Offset mode.
