My camera froze while using it so I removed the batteries so the lense would close. When I turned it back on again it says I needed to reformat the memory card. Is there any way to retrieve the photos that were already on the card before reformatting?
Have a look on one of the major shareware/freeware sites (FileHippo, MajorGeeks, CNET) for a photo recovery utility. You'll probably also need a card reader that connects to your computer by USB but these are pretty cheap.
