I am having trouble setting up my exteral USB drive to be writable by me. The root directory is owned by root and the ls -l looks like this: ls -Rl /media/ /media/: total 4 drwxrwxrwx+ 2 root root 4096 Aug 14 18:34 chrisWhat is the "+" at the end of the file permisssions? Is that what's preventing me from writing? I am user chris. I suppose I could just do a chown chris to the directory, but it doesn't make sense to me still why I can't write to it now.
