So here's my current problem. I have attached an external USB drive. The name, in /media/mcc, is a 24-digit GUID. I would like it to be something shorter, such as "chuchu"*. I believe in Ubuntu I could do this by right clicking the drive in GNOME and saying "Rename". The Debian IRC asserts:

1. That Debian doesn't have this feature;
2. That it does have it, but I need to be a GNOME "privileged user". They can't explain what this means.

How do I do this?

* My laptop's name is "Anthy".
