Thanks guys for those answers, I simply hope if you define ATAPI-8 with requirement of MMC4 version 2 support, I really hope there will be an additionnal command defined by T13 forum that gives the version.sub-version.release of this MMC "standard". If you have some time to inquiry to people making CD/DVD burning software you'll find the list of ALL possible drives, each one having some specific call (acceptable) and specific way to answer to "standard" MMC (quite boring). Could this be avoided for serial ATAPI while stepping with a possible clean standard ? One other point is : as Hale said "SATA is not compatible with PATA". Could it be that serial ATAPI could be more compatible with parrallel ATAPI (plus the requirements for better filtering the multimedia calls) ?

That question is answered. T10 has now accepted into itself the paradox of contradiction. For example, T10 SPC offers a definition of op x12 Inquiry, and T10 MMC offers a competing definition. So we no longer need to talk about SFF and T10 offering two standards that differ only enough to be binary incompatible. Now T10 itself does that. Beyond the many explicit contradictions, some implicit contradictions may remain. For example, I haven't yet seen anyone but me publish the fact that most ATAPI hosts overwrite unallocated memory if asked to pass thru such popular, and by-t10-legitimate, cdb/ data length combinations as: -i x05 -y "12 00 00 00 05 00" // Inquiry up thru offset 4 Addi. Length -i x12 -y "03 00 00 00 12 00" // Default Win XP/2K auto sense Pat LaVarre
