7.2.5. RECEIVE DIAGNOSTIC RESULT command
Whenever a diagnostic test is executed, the drive automatically prepares a diagnostic test result that can be
returned to the host computer when a RECEIVE DIAGNOSTIC RESULT command is issued.
If the PF bit in the SEND DIAGNOSTIC command was sent to one, the diagnostic test result will be preceded by a
four-byte header which will be of the form:
