I'm in class. 72 pictures due by noon. My sd card went corrupt, half my pics come up 'unexpected end of file' when trying to open in ACR or lightroom. The file sizes are noticably smaller. I also can't get the card to open in a card reader. It only opens when loaded in the camera and connected to the computer. I can see the pics in the camera LCD, and they appear fine. Ideas? Thoughts? Anyone have any recovery software they could host? I'm desperate. thanks!
