The following defines the 512 bytes that make up the Attribute Threshold information. This data
structure is accessed by the host in its entirety using the S.M.A.R.T. Read Attribute Thresholds. All
multi-byte fields shown in these data structures follow the ATA/ATAPI-6 specification for byte
ordering, namely that the least significant byte occupies the lowest numbered byte address location
in the field.
The sequence of active Attribute Thresholds will appear in the same order as their corresponding
Attribute Values.
