The SMART Disable Operations subcommand disables the Autosave feature along with the S.M.A.R.T. operations of the device. Upon receipt of the subcommand from the host the device asserts BSY, enables or disables the Autosave feature, clears BSY, and asserts INTRQ. 15.32.4 S.M.A.R.T. Save Attribute Values (Subcommand D3h) This subcommand causes the device to immediately save any updated Attribute Values to the Attribute Data sector of the device regardless of the state of the Attribute Autosave feature. Upon receipt of the S.M.A.R.T. Save Attribute Values subcommand from the host the device writes any updated Attribute Values to the Attribute Data sector. 15.32.5 S.M.A.R.T. Execute Off-line Immediate (Subcommand D4h) This subcommand causes the device to immediately initiate the set of activities that collect Attribute data in an off-line mode (off-line routine) or execute a self-test routine in either captive or off-line mode. The Sector Number register shall be set to specify the operation to be executed. Sector Number 0 1 2 127 129 130 Operation to be executed Execute S.M.A.R.T. off-line data collection routine immediately Execute S.M.A.R.T.

Short self-test routine immediately in captive mode Execute S.M.A.R.T. Extended self-test routine immediately in captive mode Off-line mode: The device executes command completion before executing the specified routine. During execution of the routine the device will not set BSY nor clear DRDY. If the device is in the process of performing its routine and is interrupted by a new command from the host, the device will abort or suspend its routine and service the host within two seconds after receipt of the new command. After servicing the interrupting command, the device will resume its routine automatically or not start its routine depending on the interrupting command. Captive mode: When executing self-test in captive mode, the device sets BSY to one and executes the specified self-test routine after receipt of the command. At the end of the routine the device sets the execution result in the Self-test execution status byte-see Figure 122on page 164-and ATA registers as below and executes command completion.

The SMART Disable Operations subcommand disables the Autosave feature along with the S.M.A.R.T.
operations of the device.
Upon receipt of the subcommand from the host the device asserts BSY, enables or disables the
Autosave feature, clears BSY, and asserts INTRQ.
15.32.4
S.M.A.R.T. Save Attribute Values (Subcommand D3h)
This subcommand causes the device to immediately save any updated Attribute Values to the Attribute
Data sector of the device regardless of the state of the Attribute Autosave feature. Upon receipt of the
S.M.A.R.T. Save Attribute Values subcommand from the host the device writes any updated Attribute
Values to the Attribute Data sector.
15.32.5
S.M.A.R.T. Execute Off-line Immediate (Subcommand D4h)
This subcommand causes the device to immediately initiate the set of activities that collect Attribute data
in an off-line mode (off-line routine) or execute a self-test routine in either captive or off-line mode.
The Sector Number register shall be set to specify the operation to be executed.

Off-line mode
:
The device executes command completion before executing the specified routine.
During execution of the routine the device will not set BSY nor clear DRDY. If the device is in the process
of performing its routine and is interrupted by a new command from the host, the device will abort or
suspend its routine and service the host within two seconds after receipt of the new command.
After
servicing the interrupting command, the device will resume its routine automatically or not start its routine
depending on the interrupting command.
Captive mode:
When executing self-test in captive mode, the device sets BSY to one and executes the
specified self-test routine after receipt of the command. At the end of the routine the device sets the
execution result in the Self-test execution status byte—see Figure 122on page 164—and ATA registers
as below and executes command completion.
Status
Set ERR to one when self-test has failed
Error
Set ABRT to one when self-test has failed
