Comment 6 for bug 44233

This little problem just caused me to loose two days of work. I got some DVD's burned by a co-worker in Mac OSX with some data on them. When I inserted them, they mount fine as iso9660. With the exception of lower case filenames, they looked fine. However, for unknown reasons, mounting as iso9660 causes every 13th file not to be visible! The disks had very large number of files on them, so I didn't notice anything at first. It took me two days to figure out that 1/13th of my data was missing.

My point is that this little problem is not so little and can cause silent data loss. Somehow a fix should be made, but the fact that no one has been assigned this bug yet isn't promising.

I tried commenting out the cdrom line in /etc/fstab. This allows the DVD to be mounted, but it appears that the DVD contains the user, group and permissions of the original Mac user (or is automatically mounted o-rwx), so I cannot access much of the disk. Putting auto instead of udf,iso9660 fixes the problem.
