This command overwrites the maximum number of Address of HDD in a range of actual device capacity. Once device receives this command, all accesses beyond that Address are rejected with setting ABORT bit in status register. When the address requested is greater than 268,435,455, words (103:100) shall be modified to reflect the requested value, but words (61:60) shall not modified. When the address requested is equal to or less than 268,435,455, words (103:100) shall be modified to reflect the requested value, and words (61:60) shall also be modified. If this command is not supported, the maximum value to be set exceeds the capacity of the device, a host protected area has been established by a Set Max Address command, the command is not immediately preceded by a Read Native Max Address Ext command, or the device is in the Set Max Locked or Set Max Frozen state, the device shall return command aborted. If the device in Address Offset mode receives this command with the nonvolatile option, the device returns aborted error to the host. The device returns the command aborted for a second non-volatile Set Max Address Ext command until next power on or hardware reset. Output Parameters To The Device B 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 Ext command is preserved by POR. When B=0, MAX Address which is set by Set Max Address Ext command will be lost by POR. B=1 is not valid when the device is in Address Offset mode. LBA Low Current Set Max LBA (7:0). LBA Low Previous Set Max LBA (31:24). LBA Mid Current Set Max LBA (15:8).
