Table 5.10 Features Field values (subcommands) and functions (1/3)

Features Field		Function
X’D0’	SMART READ DATE:
	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 5.11.
X’D1’	SMART READ ATTRIBUTE THRESHOLDS:
	This subcommand is used to transfer 512-byte guarantee failure threshold
	value data to the host.
	* For information about the format of the guarantee failure threshold value
	data, see Table 5.12.
X’D2’	SMART ENABLE/DISABLE ATTRIBUTE AUTOSAVE:
	Enables (by setting the Sector Count field to a value other than 00h) or disables
	(by setting the Sector Count field to 00h) a function that automatically saves
	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.
	In this drive, this function is enabled at the shipment from the factory.
X’D3’	SMART SAVE ATTRIBUTE VALUES:
	When the device receives this subcommand, if saves device attribute value
	data, and transfers the RegDH, then reports the status.
X’D4’	SMART EXECUTIVE OFF-LINE IMMEDIATE:
	A device which receives this command starts collecting the off-line data
	specified in the Sector Number field, or stops.
	In the off-line mode, after transferring the RegDH, off-line data are
	collected. In the captive mode, it collects off-line data then transfers the
	RegDH when collection of data is completed.
		SN Off-line data collection mode
	00h: Off-line diagnosis (off-line mode)
	01h: Simple self-test (off-line mode)
	02h: Comprehensive self-test (off-line mode)
		03h: Conveyance self-test (off-line mode)
	04h: Selective self-test (off-line mode)
	7Fh: Self-test stop
	81h: Simple self-test (captive mode)
	82h: Comprehensive self-test (captive mode)
		83h: Conveyance self-test (captive mode)
		84h: Selective self-test (captive mode)
