I burn my backups on to CD and DVDs using Nero. Yesterday when I inserted one of the previously burnt DVDs into the DVD drive, Incd automatically ran and instead of Windows XP asking me what I wanted to do with the disk (usually open pictures with windows explorer etc), I got the message about what I wanted to burn to blank disk. I tried to view the images using photoshop but nothing appeared. I tried some of my other backup disks and I got the same message each time with nothing showing on the disks. BTW I have often previously viewed and copied files from these disks back to my pc. After googling, I assumed the problem was with Nero and Incd so I used the Nero clean tool to uninstall Nero from my pc. Now I can use most of the disks as per normal but there are still a couple where the computer doesn't seem to recognise that there is anything on them. Is there anything I can do? Do you think the data on these disks has gone forever? Any thoughts would be gratefully received.
