7.3.3 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.
7.3.3.1 Data Structure Revision Number
This value is the same as the value used in the Device Attributes Values Data Structure.
7.3.3.2 Individual Thresholds Data Structure
The following defines the 12 bytes that make up the information for each Threshold entry in the Device Attribute Thresholds Data Structure.
Attribute entries in the Individual Threshold Data Structure are in the same order and correspond to the entries in the Individual Attribute Data
Structure.
7.3.3.3 Attribute ID Numbers
Attribute ID Numbers supported by the device are the same as Attribute Values Data Structures.
7.3.3.4 Attribute Threshold
These values are preset at the factory and are not meant to be changeable. However, the host might use the "S.M.A.R.T. Write Attribute
Threshold" subcommand to override these preset values in the Threshold sectors.
7.3.3.5 Data Structure Checksum
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.
