12.17.2 Extended Comprehensive SMART Error Log
The figure below defines the format of each of the sectors that comprise the Extended Comprehensive SMART

12.17.2.1 Error log version
The value of this version shall be 01h.
12.17.2.2 Error log index
This indicates the error log data structure representing the most recent error. If there have been no error log entries,
it is cleared to 0. Valid values for the error log index are 0 to 4.
12.17.2.3 Extended Error log data structure
An error log data structure shall be presented for each of the last four errors reported by the device. These error log
data structure entries are viewed as a circular buffer. The fifth error shall create an error log structure that replaces
the first error log data structure. The next error after that shall create an error log data structure that replaces the
second error log structure, etc.
Unused error log data structures shall be filled with zeros.
