15.32.13 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 are in byte ordering—that is 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.
