Problem and solution: 16GB Compact Flash in EOS 30D

Transcend 16GB Compact Flash

Today I got the 16GB Compact Flash card that I ordered a few days ago. I just wrote about the crazy weather but this is almost even more insane: 16GB now cost me less than half of what my two 2GB cards cost me two years ago. And back then I had a serious discount since I bought them at the shop I worked at, Allradio. That means that the price per GB is now less than a tenth of what it was two years ago!

Eager to try it out (why? don’t know) I put my 16GB card in my camera, formatted it and … Oh! It now only had 8GB of space.

It turns out, the Canon EOS 30D doesn’t cope with (formatting) cards larger than 8GB. And when the card had been formatted down to 8GB it couldn’t be reformatted to 16GB. Not in the camera, not in Windows.

After hunting around for a while, giving up, and then hunting around some more, I found a solution: A small program called USB_Format. Just unzip it and run it, and it should let you reformat your memory card in your card reader to it’s proper size.

Now I just have to remember not to format the card in the camera. But that shouldn’t be so hard. I don’t usually format, I tend to Delete all instead.

    Thank you for this timely post. I just bought a 16Gb card for my Rebel XT and run into the exact scenario you described.

    David, finally a post that really helped. Thank you. 99% of the other posts on the internet for the same problem just tell people that they have been duped, and the cards are really only 8GB.

    It’s funny that I just had this very same problem on the Canon 350D/Digital Rebel XT and a quick search pointed to your blogpost. Thank you so very much.

    I’m so glad I wasnt the only one having this problem! I tried what you said but it’s still telling me I have 8gb on my card… Would you by any chance have any idea what I’m doing wrong? Thanks!

    Anonymous, it was a while since I did this … is there any where you can choose to format 16 GB instead of 8 GB? Doens’t that work?

    Thanks for the info, great timing – that tool worked great for me. I had no idea windows refuses to handle multi-partition removable drives.

    Had this problem with my Rebel XT. My 16GB card was already formatted as 16GB when it arrived. But after using it for a while I formatted it on the Rebel XT (firmware 1.0.3). I realized it had an issue because it formatted it to 8GB even though it showed 15.0GB as the size of the card.Then the PC shows it as 2 separate 8GB partitions and wouldn’t format it to 16GB – but that tool worked great. Thank you so much.

    Just updated my Canon 30D to the new firmware 1.0.6 and it worked like a charm. I formatted my 16GB card to a full 16GB in my camera. Thanks Canon! This was the first time I really needed a firmware update.

    Ah, great! This settled up some contradictions I’ve heard.

    Cheers mate, same problem. I had a whopping 8gb of my 16gb being unusable for the past 2 years till I found your solution. Can’t thank you enough.
