NO PREVIEW AVAILABLE

Before formatting a friend’s computer, I copied all of their valuable pictures to some cd’s. When they were copying them back in after the format, there was one cd where all of the pictures came up with ‘No Preview Available’ when they were opened. Of course this cd had to be the one they needed. I am trying desperately to find out what is wrong. I have gogled it and have not found an answer. I copied these pics in the same sammer as the other pics. Can anyone help? I would appreciate it very much.
