I have an 8gig duo pro card which was working fine. I took it to a photographic centre to burn pictures onto CD. After that I am getting a message re-insert card when I load it into the Sony Cyubershot W120 camera. I then tried my 4gig card and it was perfect. I then inserted the 8gig card into my Sony H5 camera and it gave the messag format error. Please advise what to do.
