ABSTRACT
This standard specifies the AT Attachment command set used to communicate between host systems and
storage devices. This provides a common command set for systems manufacturers, system integrators,
software suppliers, and suppliers of storage devices. This standard maintains a high degree of compatibility with
the ATA/ATAPI Command Set - 3 (ACS-3).

American
National
Standard
Approval 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CAUTION NOTICE: This American National Standard may be revised or withdrawn at any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, notice of one or more claims has
been received. By publication of this standard, no position is taken with respect to the
validity of this claim or of any rights in connection therewith. The known patent holder(s)
has (have), however, filed a statement of willingness to grant a license under these rights
on reasonable and nondiscriminatory terms and conditions to applicants desiring to
obtain such a license. Details may be obtained from the publisher. No further patent
search is conducted by the developer or the publisher in respect to any standard it
processes. No representation is made or implied that licenses are not required to avoid
infringement in the use of this standard.

Revision History (part 1 of 8)
Description
Initial revision created from ACS-3 r5
1)
2) Updated to include ANSI Editor comments
3) Abstract updated to reflect ACS-4
4) Correct Bibliography to not have an Annex header, as required by ISO/IEC
5) Restarted revision history and integrated proposals list
1)
Incorporated additional editorial fixes inspired by the ANSI Editor (e.g.,
'users' to 'the users' in page footnote for JEDEC, corrected spelling
INCITS in definition of T10 acronym, fixed second unordered list in 4.9.2,
'self-routine' to 'self-test routine' in 7.46.5.2.8, corrected of a plethora of
commas and periods on phrases such as “In figure 5,” remove periods
from various non-sentences such as “Reserved.”, add “i.e.,” addition of
'field' after a small caps field name). To reduce confusion, some of these
NOP changes were not marked with change bars.
Incorporated T10/14-027r1 – Security Protocol code request for Secure
Content Storage Association.
Incorporated f13104r6 – Pending Defects Log.
Incorporated f13105r2 – Clearing Flagged and Pseudo Uncorrectable
Errors.
Incorporated f13129r6 – Workload Utilization Device Statistic.
Incorporated f13132r0 – Residual Spec Concerns About Endurance.
Incorporated f13144r7 – Utilization Usage Rate Information.
Incorporated f13156r0 – Fix the Security Command Actions Table.
Incorporated f14102r0 – Correct Check Power Mode Normal Output table.
Incorporated f14111r0 – Removal of NCQ requirement for Partial to
Slumber Transition.
1)

3)
4)
5)
6)
7)
8)
9)
10) Added cross references where possible in SMART Read Data table.
11) Added a missing 'field' in 9.21.6.
1)
Incorporated f14118r0 – Remove ATAPI from ACS-4, with following notes:
A) several oversights in f14118r0 were detected and repaired as a
result of broken cross references;
B) multiple descriptions that involved the DEVICE RESET command
and IDENTIFY PACKET DEVICE command were missed by
f14118r0 (mostly in the power management model), and most were
expunged during incorporation, with those which survived being
given a “(see ACS-3)” toe tag;
C) changes were flagged with change bars wherever possible, but
places like page footers and command deletions were missed.
2) Converted to latest ISO format for Abbreviations et al. subclause.
3) Converted to latest ISO-oriented list format and conventions.
4) Converted notes and examples formats to ISO style.
5) Converted to ISO rules for units (e.g., 30 seconds s/b 30 s)
6) Changed 1,024 to 1 024 in figure 4, and 2,048 to 2 048 in figure C.3.
7) Made figure footnote references consistent in figure C.2.

Description

10) Updated the Command Code Usage Matrix table in clause 7 to account for
commands made obsolete by ATAPI removal (missed in r02); and

have type “Bytes”, which is the truth.
Incorporated the last unprocessed proposal approved by the April T13
Plenary, f14112r1 – Change Log Annex to the new Clause 9. This change
was deferred out of r02a to improve the correlation between the posted
revision and the proposals that modified it. The changes associated with
moving the Log Annex have not been highlighted with change bars
because any attempt to do so will create more confusion than illumination.
Incorporated f14136r1 – Additional command input fields;
Incorporated f14139r1 – Power Conditions log beefcake;
Incorporated f14140r1 – Post-ATAPI document relationships;
The note to entry format was applied the keywords subclause, which
included putting the keywords subclause at the same level as the
definitions subclause;
The note to entry format was applied the definitions subclause;
5)
6) SMART Command Transport (SCT) was removed from the normative
references because SCT is fully documented in this standard;
7) ACS-3 was added to be bibliography because of the various revision
numbers and bits that reference it;
8) As the precursor for HBA-2, ATA - Adapter was added to the bibliography
because various rumblings in committee suggest that HBA-2 may be
cancelled;
The normative references clause and bibliography were updated to use
the newest format;
In table 105, the field in the last row was corrected to read COMMAND
instead of FEATURE; and
9)
10)
11) Table 205 was corrected to specify log address 20h only once.
