The value of this byte defines the current status of the off-line activities of the device. Bit 7 indicates an Automatic Off-line Data Collection Status.
Bit 7   Automatic Off-line Data Collection Status
0         Automatic Off-line Data Collection is disabled.
1         Automatic Off-line Data Collection is enabled.

Bits 0–6 represent a hexadecimal status value reported by the device.
Value       Definition
   0         Off-line data collection never started.
   2         All segments completed without errors. In this case the current segment pointer is equal to the total segments required.
   3         Off-line activity in progress.
   4         Off-line data collection is suspended by the interrupting command.
   5         Off-line data collecting is aborted by the interrupting command.
   6         Off-line data collection is aborted with a fatal error.

Bit            Definition
0-3      Percent Self-test remaining. An approximation of the percent of the self-test routine remaining until completion given in ten
            percent increments. Valid values are 0 through 9.
4-7     Current Self-test execution status.
            0         The self-test routine completed without error or has never been run.
            1         The self-test routine was aborted by the host.
            2         The self-test routine was interrupted by the host with a hard or soft reset.
            3         The device was unable to complete the self-test routine due to a fatal error or unknown test error.
            4         The self-test routine was completed with an unknown element failure.
            5         The self-test routine was completed with an electrical element failure.
            6         The self-test routine was completed with a servo element failure.
            7         The self-test routine was completed with a read element failure.
            15       The self-test routine is in progress.

This field tells the host how many seconds the device requires to complete the off-line data collection activity.

This byte is a counter indicating the next segment to execute as an off-line data collection activity. Because the number of segments is 1, 01h is always 
returned in this field.

              0     S.M.A.R.T. Execute Off-line Immediate subcommand is not implemented
              1     S.M.A.R.T. Execute Off-line Immediate subcommand is implemented
1            Enable/disable Automatic Off-line implemented bit
              0     S.M.A.R.T. Enable/disable Automatic Off-line subcommand is not implemented
              1     S.M.A.R.T. Enable/disable Automatic Off-line subcommand is implemented
2            Abort/restart off-line by host bit
              0      The device will suspend off-line data collection activity after an interrupting command and resume it after a vendor 
                      specific event
              1     The device will abort off-line data collection activity upon receipt of a new command Bit Definition
3           Off-line Read Scanning implemented bit
              0     The device does not support Off-line Read Scanning
              1     The device supports Off-line Read Scanning
4            Self-test implemented bit
              0     Self-test routing is not implemented
              1     Self-test routine is implemented
5            Reserved (0)
6            Selective self-test routine is not implemented
              0     Selective self-test routine is not implemented
              1     Selective self-test routine is implemented
7            Reserved (0)
