I have a 2TB WD USB disk which I formatted with an HFS file system on my macbook. When I plug it into my PC's usb port knoppix recognizes it but only R/O. There is no paritition icon on my desktop for it, and when I click (right or left, makes no difference) on its icon in the file manager the only option I get is to unmount it. Can I mount it as R/W?
