13.32.3 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-5 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.
