Upon receipt of the subcommand from the host the device asserts BSY, enables or disables the Autosave feature, clears BSY, and asserts INTRQ. 11.33.1.4 SMART 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 SMART Save Attribute Values subcommand from the host the device writes any updated Attribute Values to the Attribute Data sector. 11.33.1.5 SMART 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 SMART off-line data collection routine immediately Execute SMART Short self-test routine immediately in off-line mode Execute SMART Extended self-test routine immediately in off-line mode Abort off-line mode self-test routine Execute SMART Short self-test routine immediately in captive mode Execute SMART 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 (Figure 142 on page 168) and ATA registers as below and executes command completion.

Upon receipt of the subcommand from the host the device asserts BSY, enables or disables the Autosave
feature, clears BSY, and asserts INTRQ.
11.33.1.4
SMART 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
SMART Save Attribute Values subcommand from the host the device writes any updated Attribute Values
to the Attribute Data sector.
11.33.1.5
SMART 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.

:
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 (Figure 142 on page 168) 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
Cyl Low
Set to F4h when self-test has failed
Cyl High
Set to 2Ch when self-test has failed
11.33.1.6
SMART Read Log Sector (Subcommand D5h)
This command returns the specified log sector contents to the host.
The 512 bytes data are returned at a command and the Sector Count value shall be set to one. The
Sector Number shall be set to specify the log sector address.
