I have a WD external HD where I save my photos plus other stuff. I think its about to die on me. So i was trying to make back up file on DVD using nero but it won't let me. It would always give me an error "failure to read file". but when I would open a file i can view it. Sometimes it takes too long to open them. I made back up files on probably 50% of the content. I already tried using a different computer but I still got the same result. I don't have any other software other than my nero. Please help... Thanks!
