A friend of mine passed away recently, and his wife asked me to copy all of his pictures onto one DVD that I can copy for his friends and family. Almost all of his pictures were on CD's (he kept hardly any on his hard drive). When I try to copy files, I am getting errors on about half the discs (Cyclic Redundancy Error). The CD's do not have any scratches, so I am not sure what is causing the errors. I have tried reading the discs on 4 different computers and keep getting the same errors.
