Anyone know anything about memory disks? I've got a Secure Digital Storage Device for my camera, which I always remove and put in my computer when I want to look at my pics. I did this last time, and all was fine. Now when I put it back in my camera, I get "Memory Disk Error" and I can't take photos or review them. Put it back in my computer and it won't let me open anything (or even acknowledge that there's content on it). It wants me to format the disk before I can use it. Well, formatting will delete all content, I know, and I'm not sure what's on it. Is there a way to fix it without formatting? Or will formatting even cure the problem?
