Ok, I found one of the backup discs of original shots of a vacation. I remember doing another and do hope that one is found and is good.

This CD has been in the home, normal temps, in a case in a rack not in the sunlight.

The opened image is the main one.  Damaged.  Totally not readable. Recovery possible? I don't have a clue but doubt it.

**But why does the thumbnail (if I choose thumbnail in the folder view instead of list, etc.) show what appears a full shot?

**I posted this in a new thread for the benefit of all who save all backups to disc, CD or DVD..a little less than 5 years took this one away from being useful.       TomDart.
