7.5.49.2. Summary SMART Error Log [Log Sector Address = 01h]
The last five 28-bit error entries that device reported are gathered in summary SMART error log. Only 28-bit
error entries contain in Summary SMART error log. The following table defines the 512 bytes that make up
the summary SMART error log. Error log data structure includes UNC errors, IDNF errors for which the
address requested was valid, servo errors, write fault errors, etc. They do not include errors attributed to the
receipt of faulty commands such as command codes not implemented by the device or requests with invalid
parameters or invalid addresses.

SMART error log version
The value of the SMART error log version is 01h.
Error log index
The error log index indicates the error log data structure representing the most recent
error. Only values 1 through 5 are valid.
First error log data structure
Second error log data structure
Third error log data structure
Fourth error log data structure
Fifth error log data structure
Device error count
This contains the total number of errors attributable to the device that have been
reported by the device during the life of the device. These errors include UNC errors,
IDNF errors for which the address requested was valid, servo errors, write fault errors,
etc. This count is not include errors attributed to the receipt of faulty commands such
as commands codes not implemented by the device or requests with invalid
parameters or invalid addresses. If the maximum value for this field is reached, the
count remains at the maximum value when additional errors are encountered and
logged.
Reserved
Data structure checksum
This is the two's complement of the sum of the first 511 bytes in the data structure.
Each byte is added with unsigned arithmetic, and overflow is ignored.
