7D won't format or read card. I've tried three of them. Is my 7D broken?

I have tried three cards and it keeps saying it can't read the card and suggested to format card. I've used three cards, two that I used yesterday just fine and a brand new one. Same result. Did i break my camera?

No, you didn't break your camera.  Your camera appears to have broken your heart, though.  If the camera cannot recognize memory cards, then it is likely to have failed in some fashion.  Call Canon U.S.Support at 1-800-OK-CANON.
