11.43.1.4
SMART Save Attribute Values (Subcommand D3h)
This subcommand c
auses the device to immediately save any updated Attribute Values to the device‟s Attribute
Data sector 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.
11.43.1.5
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
Operation to be executed
0
Execute SMART off-line data collection routine immediately
1
Execute SMART Short self-test routine immediately in off-line mode
2
Execute SMART Extended self-test routine immediately in off-line mode
4
Execute SMART Selective self-test routine immediately in off-line mode
127
Abort off-line mode self-test routine
129
Execute SMART Short self-test routine immediately in captive mode
130
Execute SMART Extended self-test routine immediately in captive mode
132
Execute SMART Selective 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 (0) 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
