Last night I wiped it with Easeus partition master, then put a new partition on it, none of my cameras recognize it now, it transfers files on my desktop fine though. I have tried different formats, but no success.
The problem is that if SD and the larger SDHC cards are to be used in a camera they have to be formatted in the camera, not in Windows.
OK, my Canon Rebel formatted it, my video cameras would not, which is where it does it's work.
The camera has formatted it for it for itself.
Can you save to it now?
Have you tried it in your computer to see if the computer recognizes it?
If it does try reformatting it as Fat 32 (a standard for most cameras)
Do not delete the partition just use a quick format.
then try it in your cameras.
You might consider if it works using check disk on it.
while in your computer after format right click on it and choose properties.
Tools tab and check disk which will give you a quick check.
