I don't know anything about Fedora -- I used to use RH9 though and from what I can tell (if you're using Nautilus) they're going to be fairly similar. If you want to browse through multiple disks you first need to know where they're mounted. The way these things work in Linux is that your first harddrive (presumably where the system is installed) is going to be "hda" (it was in RH9). From there you've got a couple of options: if you have another HDD then it'll be mount according to what's in /etc/fstab (try from the terminal, "cat /etc/fstab"). There you'll see where all your drives are mounted. If you want to browser through a CD try running user mount tools. It should be in the main gnome panel (akin to the start menu in windows). Or you could run it from the command line with "user-mount-tools" (I can't remember the exact command, but it's something like that). As for DVDs, they'll either be mounted to /mnt/cdrom or /mnt/dvd (my version of RH9 mounted CDs and DVDs to the same location). If you want to browse these disks from Nautilus go up to the "/" folder and then go to "mnt" and from there you should see "floppy", & "cdrom." By the way, the folders in /mnt will be empty if there's nothing mounted there, so make sure to mount the drives first. Hope this helps, if you've still got questions, just ask again and I can try to help.
