The first thing to do is remove the card from the camera and take it to your local photo processing location.
Tell them the problem and ask to to see if they can recover the images for you.
If they can, they can write them to a CD for you.
If they can't....you will need photo recovery software and a card reader.
A card reader will cost about $20...be sure to get one that can read xD memory cards (the type you have).
Here is one recovery software.....
It costs about $30, but it works with Windows and iMac.
To prevent this from happening in the future.
When you first put a new memory card in the camera, you must FORMAT the card with the camera before taking any photos.
To get your camera to recognize your present card....after you recover the photos......you will have to use the card reader and your computer to delete all photos and folders from the card.
Then you camera will probably recognize it properly.
Then FORMAT the card with the camera.
You are then...good to go.
I have a Fuji FinePix F20 with ALL my pictures from our recent trip to the phillipines on the card, and I've loaded past pictures onto my dad's PC fine.
When I went to load them on my imac, it didn't work and now when the card is back in the camera I am getting the "Card not initialized" error message.
I've read I need to reformat the card but I don't want to loose any of the pictures, Can anyone help me? Thanks!
