2、I Command Set (ATA8-ACS) Amendment 1SecretariatInformation Technology Industry CouncilApproved May 13, 2010 American National Standards Institute, Inc.Approval of an American National Standard requires review by ANSI that therequirements for due process, consensus, and other criteria for approval ha

3、vebeen 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 necessarily unanimity.

4、 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 or not, from manufa

5、cturing, 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 shall have the righ

6、t 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: This American National

7、 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. Purchasers of American National Standards mayreceive current information on all standards by calling o

Printed in the United States of AmericaCAUTION: The developers of this standard have requested that holders of patents that may be re-quired for the i

10、mplementation of the standard disclose such patents to the publisher. However, nei-ther the developers nor the publisher have undertaken a patent search in order to identify which, ifany, patents may apply to this standard. As of the date of publication of this standard, followingcalls for the ident

11、ification of patents that may be required for the implementation of the standard,notice of one or more such claims has been received. By publication of this standard, no positionis taken with respect to the validity of this claim or of any rights in connection therewith. The knownpatent holder(s) ha

12、s (have), however, filed a statement of willingness to grant a license underthese rights on reasonable and nondiscriminatory terms and conditions to applicants desiring to ob-tain such a license. Details may be obtained from the publisher. No further patent search is con-ducted by the developer or p

13、ublisher in respect to any standard it processes. No representation ismade or implied that this is the only license that may be required to avoid infringement in the use ofthis standard.INCITS 452-2009/AM1-2010ATA8-ACS Amendment 1 Page 1 of 24 Replace a single row in Table 6Table 6 Block Size By Com

15、t 1Completely replace section 4.25 with the following text:4.25 Trusted Computing feature setThe Trusted Computing feature set provides an interface between a horizontal security product embedded indevices whose behavior may be authorized via interaction with a trusted host system.The following comm

16、ands are mandatory for devices implementing the Trusted Computing feature set:a) TRUSTED SEND;b) TRUSTED SEND DMA;c) TRUSTED RECEIVE; d) TRUSTED RECEIVE DMA; ande) TRUSTED NON-DATA.TRUSTED SEND and TRUSTED SEND DMA may be used interchangeably. The two commands only differ bythe type of data transpor

17、t protocol used (i.e., PIO Data-Out Command or DMA Command). Similarly, TRUSTEDRECEIVE and TRUSTED RECEIVE DMA are interchangeable (i.e., PIO Data-In Command or DMA Command).IDENTIFY DEVICE data word 48 bit 0 indicates whether or not this feature set is supported.The DEVICE CONFIGURATION OVERLAY SET

18、 command provides a mechanism to remove support for thisfeature set.The data streams and subsequent actions resulting from these commands are defined by the security protocolidentified in the command parameters. These protocols may be defined by groups outside of this standard. The intent is to stan

19、dardize the data content so it is identical across both ATA and SCSI interfaces.INCITS 452-2009/AM1-2010ATA8-ACS Amendment 1 Page 3 of 24 Completely replace section 4.26 with the following text:4.26 Write-Read-Verify feature setThe optional Write-Read-Verify feature set allows a host to control read

20、 after write behavior in a device.To enable or disable the feature of Write-Read-Verify, the host issues a SET FEATURES command with one of the following subcommand codes:a) Enable Write-Read-Verify feature setb) Disable Write-Read-Verify feature setIt is possible that the device may experience redu

23、led, the device may report command completion with no error to the host even if the data is in the device volatile write cache and not written and verified to the non-volatile media. This is important to reduce the performance degradation when the Write-Read-Verify feature set is enabled.If:a) the v

24、olatile write cache is disabled and any write command is processed by the device;b) a forced unit access write command is processed by the device; orc) a flush cache command is processed by the device,then the device shall only report command completion after the data has been verified.If the Write-

25、Read-Verify feature set is enabled and the device has not already verified the maximum number of logical sectors configured for this feature set, then after after the device has written the sectors to the non-volatile media, the device shall read the data from the non-volatile media and verify that

26、there are no errors. A read from the non-volatile media shall be performed before verification. The verification of sectors is defined as vendor specific.If the Write-Read-Verify feature set is disabled, or if the device has already verified the maximum number of logical sectors configured for this

27、feature set, then no verification by this feature set shall be performed after the device has written the sectors to the non-volatile media.If an unrecoverable error condition is encountered by the device during the write, read, or verify operation, the device shall set the Device Fault bit (see 6.2

28、.6) to one.INCITS 452-2009/AM1-2010Page 4 of 24 ATA8-ACS Amendment 1Completely replace section 4.11.6 with the following text and figures:4.11.6 HPA State Transition Diagrams4.11.6.1 State Transition FiguresThe HPA state transition diagrams are in five parts: figure 5, figure 6, figure 7, figure 8 a

29、nd figure 9.In the following state transition diagrams, the notation COMMAND (value) refers to the device receiving the command with a specific value or values. For example:d) SET MAX ADDRESS (Non-Volatile) means the device successfully processes a SET MAX ADDRESS command with the V_V field set to o

30、ne; ore) SET MAX ADDRESS (Native Max) means the device successfully processes a SET MAX ADDRESS command with the LBA field set to the native max address.If a state has a transition condition that specifies native max, then any other set max conditions imply a value less than the native max value. If

31、 a state has a transition condition that specifies neither volatile nor non-volatile, then both are implied.INCITS 452-2009/AM1-2010ATA8-ACS Amendment 1 Page 5 of 24 Figure 5 HPA Not SetSET MAX ADDRESS (Volatile)H0: No HPANo PasswordSET MAX SET PASSWORDSET MAX ADDRESS EXT (Volatile)First SET MAX ADD
