I'm sure this has been talked about before but I couldn't find anything. I just got an 8gb Ridata lightning series card, works great in my 20d but I get a Card Error in my 1D. The 1D has the latest firmware on it (1.4.0) so is there anything I can do or is just not gonna take an 8gb card? won't kill me if it doesn't....not like I need 1600 photos worth on one card.
He's partially correct. You can use at least 4gb cards in the 1d mkI. I haven't personally tried bigger cards, so I can't say. FAT16 supports up to a 4gb partition. The mkI won't let you create a partition that big in camera though.
I use a little formatting tool called "hp usb disk storage format tool" - you can search for that phrase and choose whichever site you want to download from. I format my 4gb cards on my computer and use 'em in my mkI. If I forget and format them in camera, no prob they still work, but I only get 2gb.
I use an 8gb Ridata card in my 1D. Works fine when formatted in-camera, but the camera will treat it like a 2gb card.
There's suggestions floating around about formatting the card in the computer using large clusters or something to give you more space, but I have yet to accomplish this successfully.
There's also some issues with getting the card back to 8gb after formatting it in-camera at 2gb. Sometimes it has a tendency to stay at 2gb and even a reformat in the computer just reformats it to an empty 2gb. It is possible to get it back to 8gb with some fenagling (that word looks weird typed out), but I forget exactly how to do it. It's not too difficult.
I also tried the format e: /fs:fat /a:64k /x with a 4GB card, same error as you.
I then created a 4GB fat32 partition, either on a computer or by formatting in a newer model camera then did:-
format e: /q /fs:fat
This then worked! I have a 4GB for my 1D.
e: is just the drive letter of the CF card reader in my pc, make sure you change it to whatever it is in your pc. Formatting the wrong drive can be a little upsetting, especially if it is one of your hard drives.
Does anyone know how to create a 4gb partition on an 8gb flash drive? I tried going through Windows XP's disk management, but it doesn't allow me to delete the partition, only format it.
Partition Magic doesn't recognize the flash card as a drive, only hard drives.
Just did it with my 4GB card using the "format e: /q /fs:fat" method, only thing is it would only allow me to use the 64K cluster saying the 128k was to big(?).
