4.1    SAT: Remaining Work Items (04-391r5) [Sheffield]

Bob Sheffield reviewed the status of work items remaining in SAT (04-391r5).
It was suggested that we should add a subclause dealing with endian issues.
Mark Overby advocated that the objective of SAT should be clearly stated to be
totally consistent with SPC-3, SBC-2, and SAM-3 (and SAM-2).

4.2    SAT - REASSIGN BLOCKS command (05-136r1) [Bellamy]

Wayne Bellamy presented 05-136r1, which defines the proposed mapping of the
REASSIGN BLOCKS command.  The group suggested some editorial changes. Wayne
Bellamy moved and John Lohmeyer seconded that 05-136r2 (r1 as modified) be
recommended for inclusion in SAT. In absence of objections, the motion passed

4.3    SAT - LOG SENSE command and SMART (05-142r1) [Bellamy]

Although Wayne Bellamy asked that this item be deferred to the next meeting,
the group did provide some input for his consideration.

4.4    Write Same Translation (05-177r1) [Stevens]

Curtis Stevens presented a proposal (05-177r1) on how the WRITE SAME (10) and
the WRITE SAME (16) commands are mapped for SAT.  There are features described
in his proposal that reference the SCT Technical Report (DT1701).  The latest
draft of this TR is available at

The group discussed whether the first `shall' in the description of the
operation code in the first table should be `shall', 'may' or `should'. The
majority of the group favored `should'.

Curtis Stevens moved and Ron Roberts seconded that 05-177r2 (r1 as revised) be
recommended for inclusion in SAT. In absence of objections, the motion passed

5.     New Business

5.1    SAT, START STOP UNIT command mapping (05-226r0) [Evans]

Mark Evans reviewed 05-226r0, a proposal to map the START STOP UNIT command.
Mark agreed to prepare a revision 1, including changes agreed upon during the

5.2    SAT READ MEDIA SERIAL NUMBER proposal (05-227r0) [Overby]

Mark Overby presented 05-227r0, which defines how to support the SPC-3 READ
MEDIA SERIAL NUMBER command. Mark agreed to make some minor changes, which he
will post as 05-227r1 for consideration at the June 20 meeting.

One issue discovered during the discussion of this proposal was that the
current SAT translation of TEST UNIT READY does not provide a means to
determine the presence (or absence) of the medium. Mark said that he might
bring in a proposal on fixing this issue.

6.     Review of SAT Working Draft

Chris Sarcone (Apple) noted that he and Sergio Henriques attended the meeting
in hopes that SAT (or SAT-2) would help with mapping on other bridge devices
such as those that support 1394 or USB devices. They are also especially
concerned about cache synchronization issues with regards to journaling.

Bob Sheffield led the group in a review of SAT revision 4.

Jim Hatfield requested a specific item be placed on the June 20th agenda to

7.     Review of Recommendations
