If you formatted them before installing Fedora, they would be included in /etc/fstab and a mount point probably in /mnt. If you are trying to add them after installing Fedora, you need to create an entry in /etc/fstab to auto-mount upon re-boot. By running commad:
You should see which device it/they are, you will need to add a line in fstab and make a mount point in the file system. For instance, if you want to call it "fat1", you need to make a directory where it is most appropriate like /mnt or /media, your choice, like so:
Then, if it is device "/dev/hda4", add a line in /etc/fstab like so:
/dev/hda4 /mnt/fat1 vfat defaults 0 0
Even for the quick mount suggestion in the prior post you have to make a mount point in the directory structure (file system) if it does not exit.
