10.4.8 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 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.
