DVD Filesystems

March 5, 2009 9:53 PM

What would cause certain folders to show up when a DVD is mounted under Windows (XP, FWIW), but not to show up under Linux (Ubuntu Intrepid)?

I was given the wonderful New York Times Complete Front Pages as a birthday present, but I can't see all the folders when running in Linux (when it is automounted, or the ripped image is mounted loopback). I'm aware of Rock Ridge and Joliet extensions, but AFAIR, these are for POSIX permissions and Unicode filenames respectively (and are for CDROMS).

What could be going on?

And as an addendum, how are .idx and .pdx files (indices, I presume) handled by Acrobat?

Can you list what folders/files appear on Windows and then what appears on Linux?

If those are hidden files, then by default Linux doesn't show them. Run "man mount" and then search for Mount options for iso9660. There's an "unhide" option. Not knowing Ubuntu, you probably do something like this:

mount -t iso9660 -o unhide /dev/dvd /mnt/dvd

But you can't really do anything with these files anyway, unless you're brave enough to run them through Wine.

I'm assuming 'ls -la' doesn't show them either?

knave: ls -la gave the same.

sbutler:

The option 'unhide' was promising, but to no cigar. '-t udf' doesn't mount at all, so at lease we know it's ISO9660.

While reading the man page I saw the option 'norock', to turn off rock ridge extensions, which worked.

Thanks for your suggestion.

Glad you got it to work! Re-reading my post, I said:

Not knowing Ubuntu, you probably do something like this

What I meant was:

I am not familiar with Ubuntu, but you probably do something like this

Didn't mean to cast doubt on your Linux knowledge :)

Heh;-)

I'm a bit ashamed I didn't just read the manpage to start with, but oh well...
