Thanks for the quick replies!
Camorri, the linked article actually treats mounting of ISO image files, not optical media.
Pixellany, I should have written it more clearly in my first post: I've already done all the above on the command line. mount had no surprise for me as to the location of the mount point (/mnt/cdrom), and ls -alF gave me what it gave me all the while, which is an empty directory.
Code:
/dev/sr0 on /mnt/cdrom type iso9660 (ro,nosuid,nodev,uhelper=hal,uid=1000,utf8)
However! After work I had a closer look at the mount man page and fiddled around with some options. Turns out if I pass -o nojoliet to the mount command, the files show up, albeit with ISO9660's name length limitations.
This is weird nonetheless. I've had plenty of discs from all kinds of operating systems in this machine, mostly UDF, but also numerous ISO9660+Joliet media, and unless they were badly scratched or had soy sauce etched in them, they always worked. Did M$ change their Joliet stuff in recent Windows versions? Or could this be the work of a Mac, trying to undermine established standards?
Seriously interested if anyone has an idea.
As for this particular problem, it seems to be solved (kinda). But I'd really love to get to the bottom of this.
Thanks for any further insights!
