takenaka-san FYI until your name to be added in t13 mailing list. kent >>> Gary Laatsch <[EMAIL PROTECTED]> 08/07 3:09 午前 >>> ** This is the quasi-official and semi-temporary T13 email list server. ** on Item #15. It should also be noted that part of the issue here is that currently, when an I/T Write command is issued and write cache is enabled, that if an error occurs writing that data the drive will report an aborted status on all commands after the failure occurs (of course this state is cleared by hard reset or POR). The problem arises when someone is mixing I/T and streaming write commands. How does the device know whether it should set DWE for streamed write requests or go into the "abort all commands" mode for I/T type write commands if a failure should occur. DWE is not defined on I/T write command error status. Also, correct me if I am wrong, but the Write Cache Enable in SET FEATURES controls write cache for both I/T and Stream write commands? Should there be a new command for Enable/Disable Streaming Write Cache? Doesn't address the problem above, just complicates it more. Some people still like to turn off Write Cache and this would affect Streaming Write commands. Just a thought.

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.

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. 9. Meeting Schedule 1) Long term meeting schedule The following is the proposed schedule through CY2003.
