optional statements]11. [Editors Note: Add section and diagrams to make clear the

realationsh ip 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 incons istentdocumentation is correct. Bit 1 should always be obsolete, N/A,or is it t ime for reserved]

1a October 6, 2004 1. Replaced duplicate normal outputs tables with a see clause to thefirst usage.

2. Replaced many error outputs with a see clause.3. [Editors Note: Fix N/A vs Reserved]

numeric form ordered.3. Changed all the lists to conform to the changes in #2

4. Reserved 5Ch-5Fh for TCG. This was done by added commandheaders and a reserved statement in the command section. Alsomaerked the commands with T in the command matrix table.

5. Moved Normal and Error Outputs to their own section. Commandsnow 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

1f July 5, 2005 1. Added several technical reports to the approved references. They

need to be there since they are mentioned in the body of thedocument.

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 pages]6. 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 wordfield 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

e04161 was incorporated.14. Reformatted X388HTable 116X, X389HTable 117X, X390HTable 118X, X391HTable 119X. The

command code table serves as the master. All of the commandcodes are now listed. I believe this will cause the table to bemaintained better. I also discovered some inconsistencies in thetable during the reformat.

15. Performed consnstency pass on command tables, several links havebeen corrupted.

2a December 10, 2005 1. Added cross reference to tables. This is required since severalcommands point to the same tables.

AmericanNationalStandard

Approval of an American National Standard requires verification by ANSI that therequirements for due process, consensus, and other criteria for approval havebeen met by the standards developer. Consensus is established when, in the

judgment of the ANSI Board of Standards Review, substantial agreement has beenreached by directly and materially affected interests. Substantial agreementmeans much more than a simple majority, but not necessarily unanimity.

Consensus requires that all views and objections be considered, and that effort bemade towards their resolution.

The use of American National Standards is completely voluntary; their existencedoes not in any respect preclude anyone, whether he has approved the standardsor 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 inno circumstances give interpretation on any American National Standard.Moreover, no person shall have the right or authority to issue an interpretation ofan American National Standard in the name of the American National StandardsInstitute. 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 orwithdrawn at any time. The procedures of the American National StandardsInstitute require that action be taken periodically to reaffirm, revise, or withdraw thisstandard. Purchasers of American National Standards may receive currentinformation on all standards by calling or writing the American National StandardsInstitute.

CAUTION:The developers of this standard have requested that holders of patentsthat may be required for the implementation of the standard, disclose such patentsto the publisher. However, neither the developers nor the publisher haveundertaken 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 theidentification of patents that may be required for the implementation of thestandard, no such claims have been made. No further patent search is conductedby the developer or the publisher in respect to any standard it processes. Norepresentation is made or implied that licenses are not required to avoidinfringement in the use of this standard.
