10.6.4 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. 10.6.5 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. 10.6.6 Off-line read scanning The device provides the off-line read scanning feature with reallocation. This is the extension of the offline 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. 10.6.7 Error log Logging of reported errors is supported. The device provides information on the last five errors that the device reported as described in the SMART error log sector. The device may also provide additional vendor specific information on these reported errors. The error log is not disabled when SMART is disabled. Disabling SMART shall disable the delivering of error log information via the SMART 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. 10.6.8 Self-test The device provides the self-test features which are initiated by SMART 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 SMART self-test log sector as described in the SMART self-test log data structure. All SMART attributes are updated accordingly during the execution of self-test. If 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. Deskstar 40GV & 75GXP hard disk drive specifications 82

10.6.4 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.
10.6.5 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.
10.6.6
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
.
10.6.7 Error log
Logging of reported errors is supported. The device provides information on the last five errors that the
device reported as described in the SMART error log sector. The device may also provide additional
vendor specific information on these reported errors. The error log is not disabled when SMART is
disabled. Disabling SMART shall disable the delivering of error log information via the SMART 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.
10.6.8
Self-test
The device provides the self-test features which are initiated by SMART 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 SMART self-test log sector as described in the SMART self-test log data
structure. All SMART attributes are updated accordingly during the execution of self-test.
If 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.
