Today I received a new SanDisk Extreme III 16 GB CompactFlash card from SanDisk. After putting it in my 5D, I verified it was 16GB, and then following the camera's instructions I formatted the card. Guess what? My 16GB card had turned into an 8GB card. I tried every trick I could think of to no avail and then finally gave up and called SanDisk tech support.
There I was told something rather surprising. To make a long story short the tech support lady told me that with cards that large (meaning over 8 GB) I should never use the camera to format the card. That when I did so, during the format the camera destroyed half of the card's partition data. In other words instead of one 16gb partition, it created 2 8 GB partitions, one which was not allocated and therefore not visible to the camera, or the Windows "My Computer".
Currently I am awaiting an email from SanDisk which should contain the exact instructions on how I can recover the lost 8 GB partition on the card.
Has anyone else used a 16 GB SanDisk Extreme III card yet? If not, but if you're considering buying a 12 GB or larger card, you might be aware that SanDisk warns us not to use the camera to format those large cards (using the computer is apparently ok though according to them).
