Initial revision created from ATA/ATAPI-7 Volume 1 (1532D Rev 4b). 2. Removed 3 volume structure and changed abstract to reflect a command set document3. Removed sections on signal, bit, and timing conventions4. Removed clause 5, I/O register descriptions5. Kept informative annexs A-C1September 7, 20041. Restructured all commands to conform to format agreed to in e04139r4.2. Added a section defining status bits3. Added a section defining error bits4. Added a section describing protocols5. Added a section describing interrupt reason6. Incorporated single log table e04143r0 table. Did not add wording to status that host VS pages are common between SMART and GPL.7. Removed prohibited statements from command definitions. These reside in the feature set definitions.8. Editors Note: Fix N/A vs Reserved9. Editors Note: Do a consistency pass for Body Text10. Editors Note: Do a consistency pass on mandatory and optional statements11. Editors Note: Add section and diagrams to make clear the realationship of this doc to other documents.12. Editors Note: Under Error Outputs, error bit 0 is sometimes obsolete, and sometimes N/A. I do not think this inconsistent documentation is correct. Bit 1 should always be obsolete, N/A, or is it time for reserved1aOctober 6, 20041. Replaced duplicate normal outputs tables with a see clause to the first usage.2. Replaced many error outputs with a see clause.3. Editors Note: Fix N/A vs Reserved4. Editors Note: Do a consistency pass for Body Text5.

Bit 1 should always be obsolete, N/A, or is it time for reserved1bFebruary 17, 20051. Stripped unused informative references2. Changed the definition of ordered and unordered lists to make the numeric form ordered.3. Changed all the lists to conform to the changes in #24. Reserved 5Ch-5Fh for TCG. This was done by added command headers and a reserved statement in the command section. Also maerked the commands with T in the command matrix table.5. Moved Normal and Error Outputs to their own section. Commands now have a hotlink to the tables.6. Moved IDENTIFY (PACKET) DATA to its own section (Input Data)7. Changed more of the titles to be consistent with the front cover.8. Deleted unused definitions9. Changed the general feature set to only apply to non-packet devices10. Changed the packet feature set to include all the commands in the packet feature set.11. The command prohibitions are now found in the feature set description and not with each command.12. Integrated e04127r0 This makes SATA signatures reserved with no description.1cApril 15, 20051. Added proposal e04143r1 Notes that the Host Vendor Specific pages are common to both SMART READ LOG and READ LOG EXTENDED2. Added e04130r2 Tightens the definition of SMART first polling time. Also adds a field that enables longer times.3. Added proposal e05103r0 Changes the features register to log page specific for read and write log commands4. Added e04153r1 Historical annex of command documentation to Annex B5. Added e05102r1 as amended Reserves some set features and DCO fields as vendor specific6. Added back in FEATURE SET Clause infront of the description1dJune 20, 20051. Added code 1Dh to IDENTFY DEVICE for ATA/ATAPI-7 Table 13.2. Added placeholder for reporting alignment3. Updated SET FEATURES table 41 to include reserved entries instead of just saying all other entries are reserved.4. Partially Incorporated e04129r5. Assigned Set Features 0Bh and 8Bh for the enable and disable capability. Had to make several modifications to the proposal to fill in missing pieces. Unable to fill in IDENTIFY DEVICE info, data is incomplete. Stopped incorporation1eJune 21, 20051. Modified Selective self-test description last sentence to be more clear.2. Updated definition based on WG review.3. Integrated e05133r3. This conflicts with the definition of IDENTIFY DEVICE which is defined to not return an error.4. Incorporated e04129r6. Assigned IDENTIFY DEVICE words 210-213 and DCO word 7 bit 14.1fJuly 5, 20051. Added several technical reports to the approved references. They need to be there since they are mentioned in the body of the document.2. Updated DCO to refer to TR-37 (TLC) for word 7 bit 10.3. Updated the Scope to match ATA8-AAM4. Replaced sector with logical sector in many places5. Editors Note: I do not think we should refer to logs as sectors, they are really pages6. Replaced all references to the Features register with features field.7. Replaced all references to the Sector Count register with Count field. There are some places that use the count field in calculations. These places refer to the register. I have chosen to keep the word field although I think it may read better just saying cound.8. Replaced archaic references to sector number register with references to the LBA field.9. Replaced references to LBA Low, LBA Mid, and LBA high to LBA field.10. Replaced all references to device/head or device register11. Deleted references to the device control register.12. Updated overview in clause 7.13. Updated security commands to have an output data structure where appropriate14. Updated SETMAX commands to have an output data structure where appropriate.15. Removed remaining hardware references from commands. Transport documents will have to reference 1e for notes on information that needs to move. This includes most references to BSY, RDY, DRQ, and bus.16. Implemented e04161r0 (obsoleted ATAPI overlap and queue)17. Moved host vendor specific log description into its own clause.18. Integrated e05130r019. Integrated e05131r120. Integrated e05120r2 Needed to add text to 4.21 to support the examples.2August 22, 20051. Updated SET MAX ADDRESS to indicate that on drives with a capacity that is greater than 28 bits, that issues SET MAX ADDRESS to the NATIVE MAX address clears the HPA and returns the full capacity of the drive, not just 137GB.2. Added e04132r1 Defines subcommand 03 for download microcode3. Incorporated e04162r0 Obsolete Download Microcode 4. Incorporated e05151r1 Reserve opcodes for e05106. The following resources were assigned:a. CHECK POWER MODE normal returns 40h and 41hb. IDENTIFY DEVICE data words 214-221c. New opcode B6h NV CACHE (Sorry, B8h is reserved for CFA)d. DCO data structure Word 21 bits 14 and 155. Incorporated e02126r6 WRITE UNCORRECTABLE. The following resources were assigned:e. Opcode 45hf. IDENTIFY DEVICE data words 119/120 bit 2g. DCO Data word 21 bit 136. Modified DCO to indicate that the data is not an overly, it is just data that can be used to enable or disable reporting of features as well as responding to features.7. Incorporated e05127r2 Updated the definition of the DF bit.8. Incorporated e05129r1 READ/WRITE LOG DMA EXT. The following resources were assigned:h. Opcodes 47h and 57hi. IDENTIFY DEVICE data words 119/120 bit 29. Incorporated e05132r1 Report transport standard. IDENTIFY DEVICE words 222 and 223 were assigned for this purpose.10. Incorporated e05140r0 Media Serial Number Endianess11. Performed a major re-work of the IDENTIFY DEVICE table data. Added a column to indicate applicable transport.12. Received side-band E-Mail comments from yamini resulting in the following changes:j. CFA Translate Sector Features and Count fields S/B N/A as in ATA7k. Page number was deleted from the clause reference in 4.4.113. Marked bits 15:13 obsolete. This was accidently left out when e04161 was incorporated.14. Reformatted Table 114, Table 115, Table 116, Table 117. The command code table serves as the master. All of the command codes are now listed. I believe this will cause the table to be maintained better. I also discovered some inconsistencies in the table during the reformat.15. Performed consnstency pass on command tables, several links have been corrupted.2aDecember 10, 20051. Added cross reference to tables. This is required since several commands point to the same tables.Fixed command tables to match ATA7.e05141r2 was voted in however, no document has been posted.Incorporated e05162r0Incorporated e05161r0 Editors Note: This proposal adds reporting of READ/WRITE LOG EXT, but it does not address the issue of the commands being prohibited.Incorporated e05167r0.Incorporated e05109r3 as modified by Mark EvansAddressed ATA/ATAPI-7 public review comment by inserting the statement “If write cache is enabled unrecoverable errors may not be reliably reported as they may occur after the completion of the command. “ after the statement that says the first error block is returned in the response fields.Replaced Masterpassword with Master password as per E-Mail review comment.Replaced isspecified with is specified as per E-Mail review commentAmerican National Standardfor Information Technology ¾AT Attachment - 8 ATA/ATAPI Command Set (ATA8-ACS)SecretariatInformation Technology Industry CouncilApproved mm dd yyAmerican National Standards Institute, Inc.AbstractThis standard specifies the AT Attachment command set between host systems and storage devices. It provides a common command set 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.This standard maintains a high degree of compatibility with the AT Attachment Interface with Packet Interface - 7 (ATA/ATAPI-7) volume 1, INCITS 397-2004, and while providing additional functions, is not intended to require changes to presently installed devices or existing software.ANSIINCITS. -200xAmericanNationalStandardApproval of an American National Standard requires verification by ANSI that the requirements for due process, consensus, and other criteria for approval have been met by the standards developer. Consensus is established when, in the judgment of the ANSI Board of Standards Review, substantial agreement has been reached by directly and materially affected interests. Substantial agreement means much more than a simple majority, but not necessarily unanimity. Consensus requires that all views and objections be considered, and that effort be made towards their resolution. The use of American National Standards is completely voluntary; their existence does not in any respect preclude anyone, whether he has approved the standards or not, from manufacturing, marketing, purchasing, or using products, processes, or procedures not conforming to the standards.The American National Standards Institute does not develop standards and will in no circumstances give interpretation on any American National Standard. Moreover, no person shall have the right or authority to issue an interpretation of an American National Standard in the name of the American National Standards Institute. Requests for interpretations should be addressed to the secretariat or sponsor whose name appears on the title page of this standard.CAUTION NOTICE: This American National Standard may be revised or withdrawn at any time. The procedures of the American National Standards Institute require that action be taken periodically to reaffirm, revise, or withdraw this standard. Purchasers of American National Standards may receive current information on all standards by calling or writing the American National Standards Institute.CAUTION: The developers of this standard have requested that holders of patents that may be required for the implementation of the standard, disclose such patents to the publisher. However, neither the developers nor the publisher have undertaken a patent search in order to identify which, if any, patents may apply to this standard. As of the date of publication of this standard, following calls for the identification of patents that may be required for the implementation of the standard, no such claims have been made. No further patent search is conducted by the developer or the publisher in respect to any standard it p
