13.7.4 Threshold Exceeded Condition
If one or more attribute values—whose Pre-failure bit of their status flag is set—are less than or equal to
their corresponding attribute thresholds, then the device reliability status is negative indicating an
impending degrading or faulty condition.
13.7.5 S.M.A.R.T. commands
The S.M.A.R.T. commands provide access to attribute values, attribute thresholds, and other logging and
reporting information.
13.7.6 Off-line read scanning
The device provides the off-line read scanning feature with reallocation. This is the extension of the
off-line data collection capability. The device performs the entire read scan with reallocation of the
marginal sectors to prevent user data lost.
If interrupted by the host during the read scanning, the device services the host command.
13.7.7 Error log
Logging of reported errors is supported. The device provides information on the last five errors which the
device reported as described in the S.M.A.R.T. error log sector. The device may also provide additional
vendor specific information on these reported errors. The error log is not disabled when S.M.A.R.T. is
disabled. Disabling S.M.A.R.T. must disable the delivering of error log information via the
S.M.A.R.T. READ LOG SECTOR command.
If a device receives a firmware modification, all error log data is discarded and the device error count for
the life of the device is reset to zero.
13.7.8 Self-test
The device provides the self-test features which are initiated by S.M.A.R.T. Execute Off-line Immediate
command. The self-test checks the fault of the device, reports the test status in Device Attributes Data
and stores the test result in the S.M.A.R.T. self-test log sector as described in the S.M.A.R.T. self-test
log data structure. All S.M.A.R.T. attributes are updated accordingly during the execution of self-test.
If the drive is interrupted by the host during the self-tests, the device services the host command.
If the device receives a firmware modification, all self-test log data is discarded.
13.8 Security Mode Feature Set
Security Mode Feature Set is a powerful security feature. With a device lock password, a user can
prevent unauthorized access to a hard disk drive even if the device is removed from the computer.
The following commands are supported for this feature.
