If the test completes successfully, the drive returns GOOD status. If the test failed, CHECK CONDITION status is
returned with a HARDWARE ERROR Sense Key and an Additional Sense Code of DIAGNOSTIC FAILURE set. The
Host should then send a REQUEST DIAGNOSTIC command which will return information as to which test failed
and the nature of the failure. If the test requested is not defined, not available to the requested processor, or not
executable in the current configuration, this information will be reported in the data returned by the REQUEST
DIAGNOSTIC command.
Refer to clause 7, Drive Diagnostics for more detailed information about the supported diagnostic tests and test
operations.
