You made an fstab entry for the device by editing /etc/fstab as root with a
text editor, didn't you? I put that as step 3 in my original message on
2013-06-29. One like so:

LABEL=MY_BACKUPS /mnt/backup ext3 noauto,users 0 0

...this fstab line means "The device with label MY_BACKUPS is mounted on
directory /mnt/backup , has a filesystem type of ext3, is not mounted
automatically on boot, users are allowed to mount or umount it, and it is not
auto-fscked or dumped". This allows you to mount the device as a normal user
by just doing "mount /mnt/backup", which was in the script.

USB disks can be associated with different device nodes, depending on how many
other devices are plugged in. This is the whole point of using a filesystem
label; you don't have to worry about which device node the USB disk is seen
as.

Note that if you're using udev (almost everything is), you can take a look at
/dev/disk/by-label/ and see entries in there for every block device that has a
filesystem label that's connected to the machine. You can also put
/dev/disk/by-label/A_LABEL in an fstab entry, which will work fine provided
udev is running and the device is plugged in.

One mounts the device on a mountpoint first, then one does "ls
/that/mountpoint".
