Features Field		Function
X 'D0'	SMART READ DATA:
	A device that received this subcommand saves all the updated attribute
	values. The device then transfers 512-byte attribute value information to the
	host after transferring PIOSU.
	* For information about the format of the attribute value information, see
	Table 5.10.
X 'D1'	SMART READ ATTRIBUTE THRESHOLDS:
	This subcommand is used to transfer 512-byte guarantee failure threshold
	value data to the host.

	device attribute values ("automatic attribute save function"). This setting is
	held regardless of whether the device is turned on or off. If the automatic
	attribute save function is enabled and more than 15 minutes has elapsed
	since the last time that attributes were saved, then the attributes are saved.
	However, if the automatic attribute save function is disabled, the attributes
	are not saved. Upon receiving this subcommand, a device enables or
	disables the automatic attribute save function, and transfers the RegDH, then
	reports the status.

	specified in the Sector Number field, or stops.
