Old Business 4.1 SAT: Remaining Work Items (04-391r3) [Sheffield] Bob Sheffield reviewed the status of work times remaining in SAT (04-391r3). The group discussed when SAT needs to forward to T10 Letter Ballot and what date to specify as last new technical input. It was generally agreed that a letter ballot following the July T10 meeting would require all new technical input be available by the May SAT working group meeting. 4.2 SAT REQUEST SENSE Correction Proposal (05-109r0) [Overby] In the absence of Mark Overby, discussion of this topic was deferred to the next meeting. 5. New Business 5.1 SAT - REASSIGN BLOCKS command (05-136r0) [Bellamy] Wayne Bellamy presented a proposal to define the SATL handling of the REASSIGN BLOCKS command (05-136r0). Concerns were raised that the command processing was not defined in sufficient detail. Wayne agreed to revise the proposal and changes in the algorithm were discussed as length. Wayne agreed to prepare a new revision for consideration at the next meeting. 5.2 SAT - Standard INQUIRY - PRODUCT REVISION LEVEL (05-137r0) [Bellamy] Wayne Bellamy presented a proposal to define the contents of the Standard Inquiry Data Product Revision field (05-137r0). Wanye asked if the choices represented in the proposal matched the ATA drive information known to those present, and no one complained. Several editorial problems were raised and Wayne agreed to prepare a new revision of the proposal. Wayne Bellamy moved that 05-137r1 (r0 as revised) be recommended for inclusion in SAT. Steve Johnson seconded the motion. In the absence of any objections, the motion passed unanimously. 5.3 SAT - LOG SENSE command and SMART (05-142r0) [Bellamy] Wayne Bellamy presented a proposal to map certain SMART features to the Informational Exceptions log page (05-142r0). It was noted that the proposal fails to account for the fact that SMART can be supported but disabled by ATA devices. Concerns were raised about the dependencies between the SCSI Informational Exceptions reporting (as shown in the proposal) and Information Exceptions controls in the SCSI mode page (which is not discussed anywhere). Wayne agreed to revise the proposal for consideration at the next meeting. 6. Review of SAT Working Draft Bob Sheffield led the group in a review of SAT revision 3. Several changes were noted for inclusion in the next revision. 7. Review of Recommendations Ralph Weber noted that the working group made the following recommendation to the T10 plenary: For inclusion in SAT: 05-137r1 (Standard INQUIRY - PRODUCT REVISION LEVEL) [Bellamy] 8.
