I'm having trouble with the XD memory card on my Olympus C-450 Zoom digital camera. When I have taken photos I can view them on the camera display but they do not show up on the computer when I put the card in a reader. The file found by the card reader contains 62 photos whereas the camera viewer only finds 35 which are mostly not included in the 62. I can't even buy new cards for the camera because they have changed the spec. for XD and my camera only recognises the old type. Should I just give up and buy a new camera?
