13.33.1.5 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 Operation to be executed
0
Execute S.M.A.R.T. off-line data collection routine immediately
1
Execute S.M.A.R.T. Short self-test routine immediately in off-line mode
2
Execute S.M.A.R.T. Extended self-test routine immediately in off-line mode
127
Abort off-line mode self-test routine
129
Execute S.M.A.R.T. Short self-test routine immediately in captive mode
130
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 118 on page 174) and ATA registers —
see definitions below — and then executes the command completion.
Status
Set ERR to one when the self-test has failed
Error
Set ABRT to one when the self-test has failed
Cyl Low
Set to F4h when the self-test has failed
Cyl High
Set to 2Ch when the self-test has failed
13.33.1.6 S.M.A.R.T. Read Log Sector (subcommand D5h)
This command returns the specified log sector contents to the host.
The 512 bytes of 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.
