Description of problem:
I just installed a new Memorex dual format dvd+r/rw drive on a
computer which already has a regular dvd drive and a cdwriter (the
drives are cdrom2, cdrom1 and cdrom, respectively).  The new drive
plays regular cds and dvds just fine, but when I attempt to access a
dvd+r (recorded on a windows xp machine) mounted as a user I get:

[ds264@caliban /mnt]$ cd cdrom2
cdrom2: Permission denied.

Also, for some reason, the permissions change to:
dr--r--r--   2 4294967295 4294967295 1792 Dec  9 15:53 cdrom2
as opposed to:
dr-xr-xr-x   1 root root 2048 Dec 31  1969 cdrom2
which i get for any other media type.
Finally, when I mount the disk as root, I am able to access it and
view the files on it but the permissions look the same as when I mount
it as a user.

The relevant part of my fstab looks like this:
/dev/cdrom2  /mnt/cdrom2  udf,iso9660 noauto,owner,kudzu,ro 0 0
I have tried changing it to:
udf,iso9660 user,noauto,owner,kudzu,ro 0 0
udf,iso9660 users,unhide,noauto,owner,kudzu,ro 0 0
with no effect.
I have also tried running chmod 777 /dev/hdb (this is the drive in
question), also to no effect.

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1.Place DVD+R into drive
2.mount /mnt/cdrom2
3.cd /mnt/cdrom2

Actual Results:  permission denied

Expected Results:  should have been able to access the drive

Fedora Core 2 has now reached end of life, and no further updates will be
provided by Red Hat.  The Fedora legacy project will be producing further kernel
updates for security problems only.

If this bug has not been fixed in the latest Fedora Core 2 update kernel, please
try to reproduce it under Fedora Core 3, and reopen if necessary, changing the
product version accordingly.

Thank you.

I see this in FC3 kernel 2.6.11-1.14_FC3smp.  If mounted udf, I see the above
behavior.  If mounted iso9660 it works.  Disk claims to be in Joliet format
(according to the label on it).
Comment 3 Dmitry Savransky 2005-05-25 13:36:07 EDT
This problem went away after a clean install of Fedora Core 3 for me.
Comment 4 Orion Poplawski 2005-05-25 13:57:51 EDT
Mine is a fresh install as well.  What kernel and what filesystem are your dvd's
being mounted with?  Also, could you list your /etc/fstab entry for the dvd
device?  Thanks!
