What to do if I get the message on my Fujii FinePix2650"Card not initialized"?

"Card not initialized" means that you have to format the card in the camera.

This totally sucks. I have a similar issue with my Canon Vixia HF R20 and I'm using a Lexar Pro 64Gb 133x SDXC card. When trying to initialize the card, its fails and says "Process terminated with error." It also says "check the memory card" when I first put it in. Write-protect is off. My other SanDisk class 4 SDHC card seems to work ok.
I could have sworn it worked before and I was able to transfer videos to my Mac on 10.6, but I can't remember for sure if I was using the SDXC card or just the built-in memory. Very frustrating.

Try using a separate card reader to download your pics.

The S7000 cannot handle cards larger than 2GB.
If you need 4GB you can also fit a 2GB type 2 compact flash card which is the american standard.
For europe you will get a type 1 card this will also fit it is just slightly thinner.

check your card on some card reader whether its reading well or not, if not its the problem of card

What size is the SD card?

go into the settings on your camera, then format your card ive had sane problem i was told this by fuji
