I was testing the interoperability of burning a DVD-R on my mac desktop with reading it on FreeBSD 5.2.1. When I mount the DVD in FreeBSD, it gives me the following error listing the files: [root@crash]# mount -t cd9660 /dev/acd0 /mnt [root@crash]# ls -l /mnt ls: mm.21-May-2004.dump: Value too large to be stored in data type total 116002 -r-xr-xr-x 1 root wheel 440 May 25 09:54 README.mm-dump.txt* -r-xr-xr-x 1 root wheel 118786146 May 21 03:03 rt2.21-May-2004.dump* [root@crash]# df /mnt Filesystem 1K-blocks Used Avail Capacity Mounted on /dev/acd0 2374660 2374660 0 100% /mnt [root@crash]# umount /mnt Sticking the disk onto my MacOS 10.3.3 box, it shows up like this: % ls -l /Volumes/dd total 4748296 -rw-r--r-- 1 vivek unknown 440 25 May 09:54 README.mm-dump.txt -rw-r--r-- 1 vivek unknown 2312337081 21 May 03:59 mm.21-May-2004.dump -rw-r--r-- 1 vivek unknown 118786146 21 May 03:03 rt2.21-May-2004.dump The disk format is "HFS+" which is a superset of the Juliet extensions. My guess is that the file size limit is 1Gb, given that when I look at other DVD movie files, they're always broken up at 1Gb file size per segment of the movie. Can anyone confirm this? =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= Vivek Khera, Ph.D. Khera Communications, Inc.
