Hi, can anyone help. Just added some new files to a multisession disc. Have done this many times before with no problems. This time the data verification failed. Result, can't open the disc. Problem, most of the old files on the disc are no longer available to me and it's begining to look like I've destroyed my only back up. I know if I can get the old files off the disc I can start again on a fresh disc, but with the disc not opening... Well, you get the picture. Ideas anyone?
