What I asked was whether you have more than one "disc".  i.e. Can you
put a different disc into the drive and see if it acts the same?

If you put an unreadable disc in a drive, it *may* act as if you hadn't
put any disc in the drive.  It could well be that the only problem
you're having is the disc, itself.

FC5 is supposed to handle removeable media in a different way than prior
releases, and is supposed to handle it without manual user intervention
of the fstab file.

Again, this may be down to the disc.  Is it an ordinary data disc?  Do
you know if it's worked before?  If it's a multi-session burnt disc, it
may need to have the last session closed.

If you're trying an compact audio disc, they aren't "mounted".

And just for the sake of covering all possibilities, you can't read a
DVD in a CD-ROM drive.  They're physically different.

On FC4 I have something like the following.  You could try it, but then
whatever system you have on FC5 that automatically mounts removable
media might have a fight with it.

/dev/cdrom  /media/cdrom   auto    pamconsole,noexec,nodev,noauto  0 0

NB:  I think the auto-mounting system FC5 uses is tied into Gnome or
KDE, if you use them.  If you don't use either of them, you might be
fine with manual configuratin.

If you still don't get anywhere, I think your next post should include
the following, along with details about what you've tried:

      * A copy of your /etc/fstab file
      * The output from:  ls -l /dev/cd* /dev/hd* /dev/sd*
