12.38.3 Device Attribute Thresholds data structure

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 multibyte fields shown in
these data structures follow the ATA/ATAPI-6 specification for byte ordering, that is, 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.
