What is the maximum file size on a dvd+r ? System : 5.4-RELEASE-p6 Command used : growisofs -Z /dev/cd0 -l -J -r burn/ In burn/ I have a backup file of size 4166629386 bytes and some smaller files. In total 4577410 kB. growisofs ends normally : 99.88% done, estimate finish Fri May 26 23:22:48 2006 Total translation table size: 0 Total rockridge attributes bytes: 519 Total directory bytes: 0 Path table size(bytes): 10 Max brk space used d724 2287734 extents written (4468 MB) builtin_dd: 2287744*2KB out @ average 2.4x1385KBps /dev/pass0: flushing cache /dev/pass0: closing track /dev/pass0: closing session # echo $? 0 An 'ls -la' of the mounted dvd+r shows : ls: backup.bz2: Value too large to be stored in data type I can read the whole dvd without problems on a non-FreeBSD system. I cannot find a limit in GROWISOFS(1m) or MKISOFS(8), but on http://unix.derkeiler.com/Mailing-Lists/FreeBSD/questions/2005-12/msg01736.html I read about a 2 GB maximum filesize for a file on a dvd. Is this true ? If so I think it should be mentioned in GROWISOFS(1m). regards, Hans Lambermont
