I just got two new 16GB CF cards for my upcoming trip to africa. I took about 30 pictures on it to make sure everything was working fine, then I formatted it. Now the card only says 7.81GB and I can't seem to get it back to the default 16GB, regardless of whether I format it on my 30D or on my PC.
Any ideas? I'm worried about formatting the 2nd 16GB card I got.
