OK, this eemed the most suitable place to post this - During making a video, something hit the front of my digital camera, when I went to save the film a 'write error' occured, and now I can't access the memory card at all, it says 'Card Not Initialized' - I can access other memory cards just fine though.

The camera is a Finepix A345, the memory card a FugiFilm xD picture card
