** This is the quasi-official and semi-temporary T13 email list server. **
What follows is a text version of the minutes for this week's working group
meeting. I will upload them to the FTP site as soon as the FTP site lets me.
During the editorial review, a number of non-editorial issues and action
items were encountered. Everyone who is planning to attend the August
plenary is encouraged to review these issues and action itens and be
prepared to address them. Also, we would like to do a change bar review of
revision 2 that will be out next week and a line-by-line of Annex C. If
folks can review these ahead of time our likelyhood of completing these
tasks improves.

Results of the Meeting
1. Opening remarks
Pete McLean, the T13 Chairman, called the meeting to order at 10:00 A.M. on
Tuesday, July 24, 2001. Pete thanked Ron Salmon of Phoenix for hosting the
meeting.
As is customary, the people in attendance 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.
2. Approval of agenda
The agenda as reflected in these minutes was approved unanimously.
3. Membership and attendance
The Chairman reviewed the rules for membership and attendance. Attendance
at a working group meeting does not affect membership status in T13.
The following members were in attendance:
Dan Colegrove IBM Gary Laatsch Phoenix
Mark Evans Maxtor Ron Salmon Phoenix
Pete McLean Maxtor Greg Elkins Qlogic
Tony Goodfellow Pacific Digital Bob Chang Sandisk
Curtis Stevens Pacific Digital Tasuku Kasebayashi Toshiba
4. Document distribution
The following documents were distributed:
Agenda
In addition diskettes were passed around with soft copies of the above
documents.
5. ATA/ATAPI-6 project 1410-D, revision 1e
1) Editorial review of the document
The editor reviewed the current revision of the draft standard.
During the review many modifications and corrections were recommended which
the editor agreed to include in the next revision of the draft standard.
Change bars will identify text changes only.
Dan Colegrove moved and Ron Salmon seconded that the working group recommend
to the T13 Plenary that the editorial changes made at this meeting be
incorporated into the next revision (revision 2) of the draft standard.
The motion carried unanimously.
6. Issues List
During the review of ATA/ATAPI-6 revision 1e the following issues were
identified. These issues will be resolved at the T13 plenary meeting in
August.
1. 6.6.2.3 Ultra DMA burst termination phase rules, item 2): Should
DEVICE RESET be added as something that would allow a host to abort an Ultra
DMA transfer?
2. 6.15.2 BIOS locking SET MAX, in the description for state
SM2:Set_Max_Locked: transition SM2:SM3, "T13 intends to remove this
transition in ATA/ATAPI-6." What does this mean?
3. 6.23.1 Streaming commands: The last sentence in the seventh
paragraphs reads, "The SET FEATURES command to enable/disable caching may
not affect caching for streaming commands." What should happen to the
caching function of Streaming when non-Streaming caching is disabled or
enabled? May it have an effect or shall it have no effect?
4. 7.8.3 Device Control register, Access restrictions: Curtis Stevens
proposed that access to the Device Control register when DMACK- is asserted
should be allowed, though the words in the standard prohibit this access.
5. 8.17.18 IDENTIFY PACKET DEVICE, Word 49: Capabilities, bit 9: Is
defining LBA translation supported for ATAPI necessary? Is this translation
ever used for this device type?
6. Is the Host Protected Area feature set ever used for ATAPI devices?
Shouldn't this function be done via SCSI methods for these devices? If so,
shouldn't use of this feature set be prohibited for use by these devices?
7. There was strong feeling at the working group for making the C/D and
I/O bits obsolete for READ and WRITE DMA QUEUED and QUEUED EXT.
8. The entries in the Delayed LBA Log may be affected by changes in the
Streaming Performance Parameters Log or other external environmental
factors. Should this be more clearly defined? If so, how?
9. Can sectors be removed from the log if found later to be good based
on the above exceptions?
10. What is the response if RC is set and the transfer time limit
expires, and what happens if RC is not set and the time limit expires.
Should all of the data be transferred? How should the error be reported?
11. How should errors be reported for Stream commands in general? When
should the task file be used for error location reporting?
12. How should the SET FEATURES subcommand for Enable/disable reverting
to defaults affect settings, e.g., Ultra DMA modes?
13. Didn't we make SMART SAVE ATTRIBUTE VALUES obsolete?
14. When should DWE be cleared after being set?
15. Which errors are reported for DWE? It is extremely difficult (and a
new requirement not placed on I/T data type commands) for devices to
maintain context for all dirty cache content.
16. Which errors go into the Write Stream Log? (see above item)
7. Review of Action Items
1. Folks should think about the value reported for READ and
WRITE MULTIPLE commands: what really should be the default value? Is it in
word 47 or 59 in IDENTIFY DEVICE data?
2. What is the value in word 59, bits (7:0) in IDENTIFY DEVICE
data (i.e., the current multiple value) at power-up or after a hardware
reset, if bit 8 in word 59 is set to one?
3. Mark Evans is to come up with a clear definition for the
self-test failure checkpoint byte (see 8.30.8.5.3 and 8.55.6.8.4.2).
8. Call for Patents
The Chairman explained the patent policy. A document is available from
ANSI, "Procedures for the Development and Coordination of American National
Standards", at no charge. This document is also on the WWW at
ftp://www.ncits.org/help/ansi_sdo.html. Section 1.2.11 contains the ANSI
patent policy. Amy Marasco manages patent issues for ANSI and can be
contacted at [EMAIL PROTECTED] or 212-642-4954.
The Chairman then called for patents and/or patent applications that may be
necessary to comply with the requirements in T13 standards, draft standards,
technical reports, or draft technical reports.
There were no responses to the call for patents.
