Table 7: Supported commands (Continued) Command name Security Freeze Lock Security Disable Password Command code (in hex) F5H F6H 4.1.2 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 27. 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-6 Standard.
