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.
