Attribute ID Numbers supported by the device are the same as Attribute Values Data Structures.

These values are preset at the factory and are not meant to be changeable. However, the host might use
"SMART Write Attribute Threshold" subcommand 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.
