External USB HD

An old HD from my Windows age has been resurrected in the form of a USB external drive. unfortunately, I can’t access all files on Windows due to an autorisation problem and can’t mount it with openSUSE at all.I get an error message (Screenshot on Flickr - Photo Sharing!). the first part is grayed out because I’m (practically) sure it’s not true. However, I don’t really get the instructions. Could you please help?

Thank you,
calixte
