Results of the Meeting
1 Opening remarks
Pete McLean, the T13 Chairman, called the meeting to order at 9:00 A.M., Tuesday, April 24, 2001. He thanked Marc Noblitt of Seagate for hosting the meeting.
As is customary, the people attending introduced themselves and a copy of the attendance list was circulated. Copies of the draft agenda were made available to those in attendance.
The Chairman briefly reviewed the meeting rules: T13 is a Technical Committee of NCITS and operates under NCITS rules. Anyone with interest in the work of the committee is free to attend and take part in discussions. However, motions and votes are limited to member organizations, one vote per member organization. In addition, the committee complies with NCITS antitrust guidelines. As a result discussions about unannounced products, prices, volumes, vendor relations, etc., are prohibited. The Chairman noted that a set of Policies and Procedures for NCITS are available at the www.ncits.org site under the standing documents category as SD-2. The committee is operating under these revised policies and procedures augmented by the T13 procedures at the T13 web site www.t13.org.
The Chairman reported that he has now been officially appointed chair of T13 by NCITS. Dan Colegrove of IBM has been asked to serve as Vice-chairman and has accepted. Mark Evans of Maxtor has been asked to serve as Secretary and has accepted. There were no objections to these appointments.
Dan will be responsible from this point forward for issuing document numbers, maintaining the document list and web site, and assembling the mailing. Dan’s contact numbers are:

Agenda and document directory
D1410R1B ATA/ATAPI-6 rev 1b
E01116R01 Project proposal for ATA/ATAPI-7
E00138R3 Proposal for a general purpose logging feature set
D99128R10 Proposal for streaming data transfer feature set
In addition diskettes were passed around with soft copies of the above documents.
6 Review of previous action items
- Pete McLean will alert Jim Hatfield of the change to make e00159r2 mandatory for devices that do not implement the packet command set. – This was overcome by events because the words became obsolete with the inclusion of the proposal to obsolete CHS addressing.
- Mark Evans will investigate the inadequate definition of the “self test checkpoint byte” in Table 52. – Completed, will be covered in item 7.4.6.
- Pete McLean will forward project proposal for ATA host adapters (e00155r1) to NCITS for further processing. – Completed, will be covered in item 7.6.
- Pete McLean will create an ATA/ATAPI-7 project proposal draft with space for the committee to suggest features that will be considered for this next major revision. – Completed, will be covered in item 7.7.
- Pete McLean will create and send the letter ballot on e01112r1. – Completed, will be covered in item 7.9.
- Pete McLean will determine if IBM’s previous letter of blanket ANSI patent policy compliance will apply to ATA/ATAPI-6 and later. – Completed, will be covered in item 10.
7 Old business
7.1 Status of Protected Area Run Time Interface Extension Services, project 1367-D (NCITS 346-2001)
Protected Area Run Time Interface Extension Services has been published as NCITS 346-2001. This is a completed project and will be removed from future agendae.
7.2 Status for EDD, project 1386-D (NCITS 347-200x)
The project completed public review without comment. NCITS is meeting this week and this project is on their agenda for final NCITS approval.
7.3 Status of Address Offset Feature Technical Report, project 1407-DT (NCITS TR-27)
NCITS is meeting this week and this project is on their agenda for final NCITS approval.
7.4 ATA/ATAPI-6 project 1410-D
7.4.1 Audio/Visual Model (d99135r5) [Bulik]
There was no update at this meeting. Darrin Bulik said he would have a new revision by or before the June working group meeting.
7.4.2 Proposal for a General Purpose Logging Feature Set (e00138r3) [Puri]
Sumit Puri reviewed the latest version of his proposal including updates recommended at the last meeting.
“3.1.x Reassigned Sector:…” in the proposal was changed to “3.1.x Delayed LBA: Any sector for which the performance specified by the Streaming Performance parameters log is not valid.” Sumit will change all related text in the proposal to be consistent with this.
It was decided that extended logs would include all error and self-test entries, and the “28-bit” logs would contain only entries for “28-bit” commands. This will probably require additional clarification to the definition of the “28-bit” logs. Sumit will check on this.
The next revision of this proposal will include definitions for the extended comprehensive and extended SMART self-test logs and other recommendations from the working group discussions.
Curtis Stevens moved and Dan Colegrove seconded that the next revision of this proposal (e00138r4) be included in the next revision of the draft standard. The motion passed 13:0:1.
7.4.3 Proposal for a Media Maintenance Feature Set (e00139r1) [Puri]
This proposal was rejected at the previous meeting and this item will be removed from the next agenda.
7.4.4 Single device configurations ( ) [McFerrin]
Bill McFerrin explained that he thought there was an issue with register “shadowing”. He said there was an inconsistency between ATA/ATAPI-5 and ATA/ATAPI-6: A/A-5 allows shadowing, and A/A-6 prohibits registers from being shadowed.
Curtis Stevens said that he thought the change was made because some Device 0 devices will respond to a write to a Device 1 Command register. This is particularly odious for IDENTIFY DEVICE commands issued during a boot process.
Pete McLean said that he had spoken with Jeff Wolford from Compaq who said that they were looking to see if they could construct a proposal to resolve this issue. Anyone interested in contributing to the Compaq effort should contact Jeff.
There was discussion about possibly putting unique identifying values in Sector Count or Sector Number, or Cylinder High or Low registers at boot time to allow a device to report whether it was a “legacy” device, a Device 0 that did not detect a Device 1, a Device 0 that did detect a Device 1, or a Device 1. Bill said that his hardware couldn’t do this. Curtis said that he recalled from a previous discussion at a working group that some software required the values to be in those registers as they are defined today.
Several folks said they would double-check to determine the impact of defining new signature values for Command block registers and that this would be discussed at the next meeting along with any proposal that might be submitted from Compaq.
7.4.5 Cable detection issues (e01106r0) [Pryor]
Mark Evans moved and Greg Elkins seconded that e01106r0 be included in the next revision of the draft standard.
Based on discussion at the meeting the editor agreed to change references to bits specifying levels of ATA standard compliance are to be something like “compliance to ATA-3 or a subsequent standard” when the proposal is included in the next revision of the draft standard.
Because this proposal was originally submitted after the “cut-off” date a “two-thirds vote” was required to pass. The motion passed 13:0:1.
7.4.6 Self-test checkpoint byte ( ) [Evans]
Mark Evans recommended that the definition for the byte be clarified by changing it to: “Content of the self-test failure checkpoint byte may contain the number of the segment that failed during the self-test. When the segment that failed cannot or need not be identified, this field shall contain 00h.”
Based on the positive response from the committee to Mark’s recommendation, the editor agreed to make this modification to the next revision of the draft standard.
7.4.7 ID words 60-61 and 100-103 ( ) [ ]
Pete McLean explained that an issue has been identified where some BIOSs will hang during boot if words 61:60 of its IDENTIFY DEVICE information contain 0FFFFFFFh (which is the content that is specified in the current draft standard for that word when a device’s capacity is greater than 137GB).
