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 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
National
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
Standard
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CAUTION NOTICE: This American National Standard may be revised or withdrawn at any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.

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.

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)

Revision History (part 2 of 8)
Rev Date Description
02a 22-May-2014 1) Incorporated f14112r1 – Impending Failure Status to SCT Command
Status Log [this proposal lacked many of the editorial niceties (e.g., a
sentence introducing a table, and thus it was edited heavily];
2) Incorporated f14114r1 – Clarification of relationship between SET
FEATURES & SCT FEATURE CONTROL;
3) Incorporated f14115r1 – DOWNLOAD MICROCODE DMA Mode F;
4) Incorporated f14116r1 – Identify data form factor additions;
5) Incorporated f14109r3 – Connecting the SMART EX OFF-LINE IMMED
dots;
6) Incorporated f14120r1 – IDENTIFY DEVICE data word 53 PATA/SATA/…
cleanup;
7) Incorporated f13160r6 – Setting Default RECOVERY TIME LIMIT Field
[the editor's pen was applied several times during incorporation, especially
to achieve consistency of wording];
8) Incorporated f14108r2 – How to indicate log support requirements;
9) Incorporated f14119r1 – Device signature for Host Managed Zoned
Device;
10) Updated the Command Code Usage Matrix table in clause 7 to account for
commands made obsolete by ATAPI removal (missed in r02); and
11) Modified the Reserved “fields” in the Power Conditions log descriptor to
have type “Bytes”, which is the truth.
02b 22-May-2014 1) 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.
03 21-Jun-2014 1) Incorporated f14136r1 – Additional command input fields;
2) Incorporated f14139r1 – Power Conditions log beefcake;
3) Incorporated f14140r1 – Post-ATAPI document relationships;
4) The note to entry format was applied the keywords subclause, which
included putting the keywords subclause at the same level as the
definitions subclause;
5) The note to entry format was applied the definitions subclause;
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;
9) The normative references clause and bibliography were updated to use
the newest format;
10) In table105, the field in the last row was corrected to read COMMAND
instead of FEATURE; and
11) Table205 was corrected to specify log address 20h only once.
