Why is that? Works for me. In the case above I would type the
following to change to that directory, where ”⇥” means the ”↹” key
(TAB):
cd /me⇥4⇥
(/me⇥ will be auto-completed to /media/ and 4⇥ will hopefully be
auto-completed to ”4ae56680-7468-493e-aa40-9bb6c79f00f7”. If not, just
add one or a few more characters, 4a⇥).
But, as some people already suggested, maybe you would rather prefer
to use e2label to give it a label that makes sense to you in the first
place, like this example:
sudo e2label /dev/sde1 Backup
To just check the current label, try:
sudo e2label /dev/sde1

By the way, here's a useful trick, not directly related to this subject though:
If you run a command that need to be run as root, and you forget to
type ”sudo”, you don't need to type the whole command again and you
don't even need to use the ↑ key for editing the last command. All you
need to do is to type:
sudo !!
Looks something like this:

$ e2label /dev/sdb1
e2label: Access denied when trying to open /dev/sdb1
Couldn't find valid filesystem superblock.
$ sudo !!
sudo e2label /dev/sdb1
Backup
$
