Thanks for taking time to reply to what I now understand to be question that you have seen before. Your advice helped me understand that I did have a disc problem also. These aew RW's. Back then we who were naieve thought that RW's were fine, CD's were forever and never thought about OS's changing! Because of your advice I figured out that I only had one split file and a thousand partly unreadable ones. I abandoned the Restore and instead treated my DVD-RW's to a nice thick coat of Armourall and a polishing. I know its a destructive process but it only had to work once. I was really surprised to get at least 99%+ of the photos intact by the old cut and paste. I have 8256 photos. I am very happy. Thank you.
I now back up nightly with a 3tb Seagate external HD which seems to only add the changes to my system each night.Hope it works. When I first started looking for a solution in the Roxio forums I couldn't find anything with search. This morning I tried a trick I learned in another forum and Googled Roxio Retrieve and found half a doxen threads on this subject. Thanks for helping.
