Hi, Eric Wanchic: > Looks Great ! TAO was executed. Rob Bogus: > Thomas, perhaps you can clarify the SAO vs. TAO options and actual
Actually it is a packet write type. "TAO" and "SAO" are rather aliases for a certain behavior as it is known from good old CD media. With DVD+R there is only this one write type. cdrskin calls "TAO" a run without pre-announced size and "SAO" a run with such an announcement. MMC-5 4.3.6.2.2 "The Host views a DVD+R fragment as a fixed packet track where the packet size is 16." The following text describes command RESERVE TRACK as optional for reserving a fixed track size. > > Supported modes: PACKET SAO LAYER_JUMP That must have been wodim or cdrecord. cdrskin has no DVD DL support yet. So LAYER_JUMP is not among its announcements. > Total size: 18 MB (02:05.93) = 9295 sectors This might be one of the reasons why growisofs proposes to do that strange growisofs -M /dev/dvd=/dev/zero I had no propblems with appendable or partially filled DVD+R. But my images were a bit larger than 18 MB. If you omit option -multi with cdrskin, then the media will get closed by a MMC command "CLOSE SESSION, 101b, Finalize with minimal radius". which is described in the specs as "In order to assure maximum interchange compatibility with read only devices, Guard Zone 2 shall be recorded to a device defined PSN that approximates a disc radius of 30 mm. Suggested value: 70DE0h (462 304)." That looks somewhat like 900 MB minimum size. Nevertheless strange that a burner drive will not mount smaller images. What happens if you count the readable bytes from _not_ mounted media: dd if=/dev/hda bs=32K | wc Have a nice day :) Thomas -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
