What would make a Canon 7D not be able to read or write to any of my cards? I have tried about ten, new and old.
Possibly the card reader in the camera is malfunctioning. Bent pin, loose cable, etc. Probably requires a trip to Canon Service. Good luck.

That's interesting. I've been through two 30D, three 50D, two 5D, a 7D and a 5DII bodies without any CF card problems in the camera. If you take them out and put them in every time, like I do, maybe you're putting pressure unevenly or something.
Just to cover bases, I'd try the cards with someone else's bodies and connect the body to a computer and use camera window to make sure everything else is working.
