Personally I use the -UDF option to make an iso/udf hybrid as well as iso-level 3 and get a message that "files larger than 2GB found. These files will only be fully accessible if mounted with UDF" Just tested a disk now - on a dvd-r medium. One file of 4.3G and another of 29M If I mount_udf I see one file of 4.3G and one 29M. I find if I use mount_cd9660 I see two copies of the same file - showing as 4G each and one 29M. I don't see any difference using any of the options. -r--r--r-- 1 root wheel 4294965248 21 Apr 03:57 tester.file While that file size isn't a full 32 bit value it is close. My guess would be that the iso driver is still using a 32bit filesize df -h shows the cd9660 mounted size at 4.4G [leader:/] shane# mount_cd9660 /dev/cd0 /mnt/CD [leader:/] shane# ls -lah /mnt/CD/ total 8388612 dr-xr-xr-x 3 root wheel 2.0k 21 Apr 04:09 . drwxr-xr-x 4 root wheel 512B 6 Apr 15:40 .. -r--r--r-- 1 root wheel 29M 8 Apr 14:34 animation.mp4 -r--r--r-- 1 root wheel 4G 21 Apr 03:57 tester.file -r--r--r-- 1 root wheel 4G 21 Apr 03:57 tester.file [leader:/] shane# umount /mnt/CD/ [leader:/] shane# mount_udf /dev/cd0 /mnt/CD [leader:/] shane# ls -lah /mnt/CD/ total 4551764 dr-xr-xr-x 2 root wheel 2.0k 21 Apr 04:09 . drwxr-xr-x 4 root wheel 512B 6 Apr 15:40 .. -r--r--r-- 1 root wheel 29M 8 Apr 14:34 animation.mp4 -r--r--r-- 1 root wheel 4.3G 21 Apr 03:57 tester.file [leader:/] shane# umount /mnt/CD/ [leader:/] shane# uname -a FreeBSD leader.local 9.0-RELEASE FreeBSD 9.0-RELEASE #1: Wed Feb 15 16:03:18 CST 2012 root@:/usr/obj/usr/src/sys/GENERIC amd64
