I was out shooting today, and I snap off three pics in a row, and after the 2nd shot the shutter does not release and just abruptly stops....message on the screen read error 99....which is just a catchall for everything other than the few errors on the list, so I follow the directions in the manual to "reset" the problem, and it continues, so I tried everything I could think of, switching batteries, cleaning blah blah blah...nothing. So the last then I do is pull out the CF card blow it out and put it back now all seems ok, so it seems to be a card issue, my question is how often should this thing be reformatted? After every use, once every x number of pics?

I make a habit of reformatting the card whenever I put it in the camera (ie after downloadingto the PC). I see this as a way of ensuring that the camera is in full control of the file system and removes any nasties Microsoft might have introduced

I also format following every data transfer from my Microdrive. Reformatting a Microdrive on the Fuji S2 takes seconds and helps avoid possible drive freeze-up I have heard other photographers experience who had never done a reformat.
Other factors can cause a drive malfunction (temp, humidity, etc) but starting with a fresh formatted card each time might help reduce the chances.

Interesting the different methods. After one year of use I never formated my CF card, after dowloading the images from the camera via USB to my PC I just delete all images. Only formated my card once before first use.

I have my 10D for 9 months now, and until now I have never reformatted my CF cards. I just 'delete all' after transferring the images to the computer. Neither of my 2 CF cards (Lexar 12x and Silicon 'something' 32x(a non-established brand, nice and cheap )) have given me problems (yet).

I do things the same way as Tommy Mogren, move the shots from the microdrive to the computer, then put the microdrive back into the camera, format and then re-charge the batteries before putting everything back into the camera bag.

I think you will find you have the same problem i did.
Off to Canon and have a chat to the tech's and they will do some work on your camera to fix it.
Its some kind of intermittent problem on the 10D i had.
When you press the shutter after turning on after the third to eighth pic you get the error 99.
The mirror moves but the shutter does not.Locking the camera.
After it did it once i was right for the rest of the day or until i turned the camera off for more than 2 hrs.
Then it would reappear.
Started off as once a week now its once or twice a day.
Get em to check it out.
All the best

Hey all thanks for the assistance. Well Darren thats exactly what happened, I thought it was a card issue because thats the only step(removing the card) that cleared the problem. I hope I don't have to send it back. I do think either way that I will reformat the card after every use. Again thanks to all for your always helpful and informative responses.
