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
