Salutations

So I've had my Ipod video since christmas, and the first thing I did with it was install Rockbox. It's worked perfectly until just a couple days ago, when me and my friend were copying files onto it and it just stopped. We soon realized that his system had a couple viruses on it that did something to the Ipod, so I went in and got all my files off of it, then DBan'd it. Now Ubuntu won't mount it, even though it says it's there when I put 'lsusb' into terminal. Any ideas on how to mount it so I can reformat it?

Thanks in advance
