I tried to share some photos from my Fuji xD card with a friend a few days back, but when I inserted the card in his computer's card reader, it only asked if I wanted to format the card. I entered no, and ejected the card, but when I re-inserted it in my camera all I got was "card error!"

I have since been able to pull most of the pics off on my computer's card reader, but about 50 (all at the end) cannot be opened or previewed in any program I've tried. They appear to be the same size they would normally be, are listed as jpegs, and show date taken (via properties), but that's as far as I can get.

If anyone knows how I can save these images of a family visit, it would would be greatly appreciated!
