INCITS 397-2005 PDF

This standard specifies the AT Attachment Interface between host systems and storage devices. It provides a common attachment interface for systems manufacturers, system integrators, software suppliers, and suppliers of intelligent storage devices. It includes the Packet Command feature set implemented by devices commonly known as ATAPI devices. It also includes the Serial Transport Protocols and Physical Interconnect for AT Atachment devices commonly known as Serial ATA.

This standard maintains a high degree of compatibility with the AT Attachment Interface with Packet Interface - 6 (ATA/ATAPI-6), ANSI INCITS 361-2002, and while providing additional functions, is not intended to require changes to presently installed devices or existing software.
