Hi, some rather technical contribution:
> READ TRACK INFORMATION[#1]: > Track State: invisible This means the track was not closed but contains data. Reasoning: dvd+rw- mediainfo.cpp reports "invisible" if in the reply of MMC command READ TRACK INFORMATION neither the RT bit nor the Blank bit is set. I read in MMC-5 "6.27.3.9 Track Status: RT, Blank, Packet, and FP Bits" about DVD+R : " RT=0 : The Logical Track is the invisible/ incomplete fragment. RT=1 : The bounds of the fragment are defined within the Disc/Session Identification Zone. Blank=0 : Some non-zero number of writable units within the Logical Tracks is written. Blank=1 : All writable units within the Logical Track are blank. " and in 3.1.39 "Incomplete/Invisible Logical Track" " On a writable disc that implements a sequential recording model, a Logical Track is Incomplete if: a) It is open, b) It has a known start address, and c) Although its maximum length is limited only by the medium capacity, the Logical Track has no defined length. If the append point (NWA) of the Incomplete Logical Track is equal to its start address (i.e. the Logical Track is blank), the Logical Track is Invisible. " So i would call RT=0,Blank=0 "incomplete" rather than "invisible". Whatever, if the track was closed, then its bounds would be defined and RT would be set. On the other hand the drive should not issue info about two tracks if there is only a half one. :o) The difference between the Linux system and the OSX system could as well be about differences in the drives (if it is different hardware at all). A DVD-ROM drive will probably feel tempted to take "invisible" or "incomplete" literally. After all, the size of the first track is not finally decided yet. If it is important to make a particular DVD+R complete then one could try to issue an appropriate CLOSE TRACK command on that media. I know that cdrskin will not do that on a track which it did not open in the same program run. (One could implement -fix and then try.) It might be helpful to do what man growisofs proposes for unclosed media with closed tracks: growisofs -M /dev/dvd=/dev/zero But, well, it might also make the media unusable on any drive. One would have to try. Have a nice day :) Thomas -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble? Contact [EMAIL PROTECTED]
