3.1.2 Identify Drive command

The Identify Drive command (command code ECH) 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 the table on page 25. 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. See Section 1 of this manual for default parameter settings.

The following commands contain drive-specific features that may not be included in the Draft ATA-5 Standard.
