Can't delete files on my zen stone after upgrade

[Sabrage]

My creative zen stone worked brilliantly on the previous version of ubuntu but after I upgraded to hardy I can't delete anything from it. :confused: All the folders are marked with this "lock" symbol and it says the files nad folders can't be deleted. Is it because I upgraded instead of doing a fresh install?

Could I maybe use the termial to fix it? Where do I find my zen stone in the termial? What command should I use to delete the the files on it?

I did it! I went to the terminal, got to the media/Zen Stone directory and used rm-r to delete the folders! Sorry for posting this question without first trying for myself.

How do I un-padlock all the files and folders on my zen stone with a single command?

edit:nevermind. I just right clicked on the folder and changed the permissions. sorry....
