3、y Industry CouncilApproved May 30, 2012American National Standards Institute, Inc.AbstractThis standard specifies the AT Attachment command set used to communicate between host systems andstorage devices. This provides a common command set for systems manufacturers, system integrators,software suppl
4、iers, and suppliers of storage devices. The AT Attachment command set includes thePACKET feature set implemented by devices commonly known as ATAPI devices. This standard main-tains a high degree of compatibility with the AT Attachment 8 - ATA/ATAPI Command Set (ATA8-ACS) (seeANSI INCITS 453-2008).C
5、opyright American National Standards Institute Provided by IHS under license with ANSI Not for ResaleNo reproduction or networking permitted without license from IHS-,-,-Approval of an American National Standard requires review by ANSI that therequirements for due process, consensus, and other crite
6、ria for approval havebeen met by the standards developer.Consensus is established when, in the judgement of the ANSI Board ofStandards Review, substantial agreement has been reached by directly andmaterially affected interests. Substantial agreement means much more thana simple majority, but not nec
7、essarily unanimity. Consensus requires that allviews and objections be considered, and that a concerted effort be madetowards their resolution.The use of American National Standards is completely voluntary; theirexistence does not in any respect preclude anyone, whether he has approvedthe standards
8、or not, from manufacturing, marketing, purchasing, or usingproducts, processes, or procedures not conforming to the standards.The American National Standards Institute does not develop standards andwill in no circumstances give an interpretation of any American NationalStandard. Moreover, no person
9、shall have the right or authority to issue aninterpretation of an American National Standard in the name of the AmericanNational Standards Institute. Requests for interpretations should beaddressed to the secretariat or sponsor whose name appears on the titlepage of this standard.CAUTION NOTICE: Thi
10、s American National Standard may be revised orwithdrawn at any time. The procedures of the American National StandardsInstitute require that action be taken periodically to reaffirm, revise, orwithdraw this standard.
