Copy-Paste Not Working

view story

http://askubuntu.com – Using precise pangolin. I am trying to copy some folders from my portable hard drive to one of the partitions. The paste button is not working in the destination folder and whenever I am trying a drag-drop with my mouse, it says that I don't have permission to create there, albeit I have the root. Even the new folder button is not working. Help please. Dialogue box and Permission details attached. (HowTos)
