These values are preset at the factory and are not meant to be changeable. However, the host might use the "S.M.A.R.T. Write Attribute Threshold" sub-
command to override these preset values in the Threshold sectors.

The Data Structure Checksum is the 2's compliment of the result of a simple 8-bit addition of the first 511 bytes in the data structure.

The following defines the 512 bytes that make up the S.M.A.R.T. Log Directory. The S.M.A.R.T. Log Directory is on S.M.A.R.T. Log Address zero and is 
defined as one sector long.

The value of the S.M.A.R.T. Logging Version word shall be 01h. The logs at log addresses 80-9Fh are defined as 16 sectors long.

The following defines the 512 bytes that make up the S.M.A.R.T. error log sector. All multibyte fields shown in these data structures follow the ATA/ATAPI-
6 specifications for byte ordering.

This value is set to 01h.

This points to the most recent error log data structure. Only values 1 through 5 are valid.
