I am getting an Unable to Use Card error when I turn on my Dimage A1. I have had the camera for a couple of years and it has worked great. I have had to replace a card before when it went bad, but this seems to be a slightle different message and problem. I have replaced the card. I have formatted the card to FAT format on my computer (not FAT32) and still no luck. I know Sony is doing the support and repair for these cameras now, but I am looking for any insight into what I might try to fix this myself. I guess the next step is to send it off to Sony if no on here can help.
