14.41.2 Device Attributes Data Structure
The following defines the 512 bytes that make up the Attribute Value information. This data structure is
accessed by the host in its entirety using the S.M.A.R.T. Read Attribute Values subcommand. 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.
