Once device receives this command, all accesses beyond that Address are rejected with setting ABORT bit in status register. Identify device command returns the Address which is set via this command as a default value. 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 command aborted for a second nonvolatile Set Max Address command until next power on or hardware reset. The device returns command aborted during Set Max Locked mode or Set Max Frozen mode. Deskstar 60 GXP Hard disk drive specification 151
