unrecoverable read error

I backed up important files on DVD using Nero before erasing drive. All disks read fine but this one. All files are visible, but I can't copy or open any of the files. It would be great if there were a way to recover the files from this dvd. Thanks for your help.

Have you tried to just rip what's on the DVD to your HDD instead of trying to do a direct disk to disk copy?

Try cleaning the disk with a nonabrasive solution like eyeglass cleaner. Wipe from the center toward the edge and not in circles around the disk.

Try a different drive for reading. Some drives are much better readers than others; some are more forgiving and can recover better from read errors.
