I took a bunch of pictures and now when I go back to view them, I get a "Card Not Read" error message whenever I try to open most of them (80%). There are no thumbnails of the photos, just a cartoon landscape icon. I tried going directly to the SD Card with a reader and I get the same error message. I checked the card with SD Tools and found no problems with the card itself. BTW, the photos were taken not only with the Android camera on the X10a, but Action Snap, Camera Advance and several other camera apps. Mediascape can't find them either!
