I took some pics of my friends 11month old yesterday...and somehow between taking them and hooking the card up to my computer to take them off, something happened. When I clicked on the car on the computer, is said that it wasnt reformatted and asked if I wanted to reformat. Of course I said no! It wouldnt open though. I put the card back in the camera, and it said no images. I tried using the cable and just hook up the camera itself (just incase) and it still was just asking to format the card. Is my card shot? I ended up formating it, and now it seems fine. I took some shots this morning to test and I transfered them to my computer with no problem. Its a Transcend 4gig.
