4.3.1 Identify Device command
The Identify Device command (command code EC

) transfers information about the drive to the host following power up.
The data is organized as a single 512-byte block of data, whose contents are shown in on page 26. All reserved bits or
words should be set to zero. Parameters listed with an “x” are drive-specific or vary with the state of the drive.
The following commands contain drive-specific features that may not be included in the SATA specification.
