Hi, for what it is worth, MMC-5 has in its glossary: " 3.1.45 Logical Block Address (LBA) The LBA is the number that a Host uses to reference Logical Blocks on a block storage device. 3.1.46 Logical Sector Number (LSN) A sector's LBA is referred to as LSN in some references. "
So for getting in sync with MMC one would have to give up the distinction of LBA and LSN. Both would be -150 at MSF 0:0:0. In http://www.gnu.org/software/libcdio/libcdio.html#Sectors. i read: "fix me: LSNs can be negative up to the pregap size?" There appear MMC-LBAs below -150 with writing of CD-TEXT to the Lead-in of a SAO session. E.g. -11635. This address varies because it also identifies the manufacturer and the product type of CD media. Whatever, reading of that CD-TEXT is done via 43h READ TOC/PMA/ATIP Format 0101b. This command does not need a block address. (Details taken from libburn's doc/cookbook.txt and doc/mediainfo.txt) So i am not sure whether MSF 0:0:0 should be considered to be the lowest possible address in the context of libcdio. Have a nice day :) Thomas
