4.1.3 Identify Device command The Identify Device 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 31. 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 2.0 on page 3 for default parameter settings.

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 the table on

page 31. 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 2.0 on page 3 for default parameter settings.

The following commands contain drive-specific features that may not be included in the

Draft ATA-7 Standard.
