The following commands contain drive-specific features that may not be described in the Draft ATA-4 Standard.

3.2.2 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 below. 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 drive specifications in Section 1 of this manual for default parameter settings.

Note. If the alternate capacity jumper is installed on these drives, the drive capacity is reduced in word 1 to 4,092 cylinders.
