•Off-line data collection capability

Indicates the method of off-line data collection carried out by the drive. If the off- line data collection capability is 0, it indicates that off-line data collection is not supported.

Table 5.15 Off-line data collection capability

Bit	Meaning
0	If this bit is 1, it indicates that the SMART EXECUTE OFF-
	LINE IMMEDATE sub-command (Features field = D4h) is
	supported.
1	Vendor unique
2	If this bit is 1, it indicates that offline data collection under
	execution is aborted when a new command is received.
3	If this bit is 1, it indicates that the SMART Off-line Read
	Scanning Technology is supported.
4	If this bit is 1, it indicates that the SMART Self-test function
	is supported.
5	If this bit is 1, it indicates that the SMART Conveyance Self-
	test is supported.
6	If this bit is 1, it indicates that the SMART Selective Self-test
	is supported.
7	Reserved bits
