Try a different card.

Observe the connector inside camera, using a flashlight. If there is a bent pin take the camera to service immediately. Don't turn it on any more as we did in one similar case - creating a short circuit that damaged the camera electronics and voided the warranty.
If no visible problems, remove battery and leave it out overnight.

I seem to recall hearing that the power switch can be a problem on the 30D .. I'm not going to suggest you take it apart to clean the contacts .. better go to a Canon Dealer I think ..

1. Turn off the camera.
2. Remove the lens, battery, and CF card.
3. Allow the camera to sit without power for approximately 20 minutes.
4. Insert a fully charged battery, and turn on the camera.
5. Depress the shutter button as you would to take a picture.
Does the “ERR 99′ message appear? If it does, then the camera should be
serviced. If it does not, then please proceed to the next set of steps:
1. Turn off the camera.
2. Insert the CF card.
3. Turn on the camera.
4. Format the CF card in the camera.
5. Depress the shutter button as you would to take a picture.
Does the “ERR 99′ message appear? If so, then the CF card is the most
likely source of the issue. Try using a different card.
If the message does not appear, please complete the following steps:
1. Turn off the camera.
2. Clean the lens contacts by gently rubbing them with a pencil eraser
or soft cloth. Be careful that you do not let any debris fall into the
camera body.
3. Reattach your lens.
4. Turn on the camera.
5. Depress the shutter button as you would to take a picture.
If the “ERR 99′ message only appears when one particular lens is
attached, then that lens should be examined by a service technician.
If you see the “ERR 99′ with a different Canon lens attached, then the
camera should be serviced.

Take a look inside your camera's CF card slot. I suspect that you may have a bent pin in there. If so, you may elect professional repair (likely more than you'd be willing to pay), or you might want to try the following.
Remove batteries and card. Use a small/skinny jeweler's flat screwdriver to bend the pin back as close as possible. The jeweler's screwdrivers that you see at the dollar store will work fine. Another tool that I sometimes use is a stiff wire with a bent hook on the end to get very flattened pins started. Take your time and use as much patience as you can muster (take a breather in between if needed). Just keep nudging it upward/straighter a "tiny bit at a time". Whatever you do, don't try to unbend it with one push/nudge, you won't be able to do it.
It doesn't have to be perfect, just as close as you can get it. When it's the best that you can get it, take your flash card and "SLOWLY" insert it. The card itself should fine-align the pin. Remove the card, and verify that the pin is still straightened. If so, reinsert the card and try it out.
