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
disables 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 it 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
