Appendix B lists the internal status codes with their descriptions.
B.2 Internal Status Code
The internal status code is located at byte offset 18 of the request sense data and may
be available after certain types of failures.
_________________________ NOTE ____________________________
This byte has two formats: a byte code, and a bit flags format. The bit
flags format is used when there is no internal status code to report,
and can be distinguished by bit 7 being set.
