OK, sounds great. How do I put a label on the disk?

For ntfs, use ntfslabel (or use windows).
For ext2/3, use either e2label or tune2fs -L.

Or just use a felt-tip marking pen!

Cute but all of those are for labeling the /media/st not for labeling the /dev
which is the suggestion here. So the question here is involve the /dev and I
would like to know about that too if it is possible.

All of those do indeed write labels to the physical devices (hard disk,
pen drive, etc.). udev handles the populating of /dev during bootup.
Have a look here:
# ls /dev/disk/by-label
.... then change a label (as root) using the utility of your choice.
Reboot to urge udev to update /dev, then look at the contents
of /dev/disk/by-label again. You'll see the changed label.
