All, I have posted revision-4 of the SCSI / ATA Translation draft standard (SAT-r4) to the T10 website: http://www.t10.org/ftp/t10/drafts/sat/sat-r04.pdf It incorporates the following changes: Incorporated SAT WG proposals approved in the May plenary as follows: a) 05-109r0 REQUEST SENSE Correction Proposal [Overby] (with notes from draft review 3 May 2005); and b) 05-137r1 Standard INQUIRY - PRODUCT REVISION LEVEL [Bellamy]. Incorporated changes identified during review of the draft from SAT WG meetings and teleconferences in Apirl and May 2005 as follows: a) deleted template text from clause 10; b) added autosense to definitions; c) made "should" and "shall" keyword definitions consistent with SAS; d) clarified definition of the "unspecified" keyword; e) simplified Table-1 to better show the use of the "implemented", "emulated", and "unspecified" keywords; f) deleted text and editor's note in 8.3.1 MODE SELECT (6) command overview that discussed sharing mode page header and block descriptor; g) made significant changes to WRITE BUFFER download microcode modes - supporting modes 5h, 6h, and 7h, and specifying that the SATL issues MICROCODE DOWNLOAD only on the first WRITE BUFFER, and continues the data transfer with subsequent WRITE BUFFER commands; h) Removed the "Is NCQ enabled", "Is Queuing enabled", and "and SCSI OP Codes" columns in the write command summary table 58, modified the last two rows and table footnotes to clarify the use of NCQ and the non-packet device Overlapped feature set; i) Clarified the transfer length for the WRITE (12) command, adding that multiple ATA commands may be sent to satisfy the specified transfer length; j) Deleted the Format Device and Rigid Disk Geometry pages from the list of commonly used SCSI mode pages in Table 62 (because SBC-2 made them obsolete); k) Moved the INQUIRY VPD pages subclause from the primary commands clause (8) to the device parameters clause (10), and modified the heading levels to match; l) Added a glossary entry for ATA queued commands and used it in the commands overview clause (7) in the description of the requirement for a SATL to queue internally any commands that are not ATA queued commands; m) Miscellaneous editorial changes; and n) Added table-50 listing the mode page translations defined in the SAT standard.
