Does it have any partitions? Look in Disk Management.
It may be that it's a mis-labeled 10 GB card.

also, is it showing 10gb in the computer, or just phone? my phone only supports 6 gb so i cannot see all of my 8gb card. if its showing just 10 in computer, ignore this comment. Actually, delete it...

after taking everything off the card, Just use disk manager and right click and delete both partitions, then it should combine them to give you 1 large unformatted partition, then try formatting it in the camera options

If you still have problems, use a program like gparted and reformat the flash drive.

after that, save enough data to fill it then check by randomly opening files if all of the data is still there.

some counterfeit sd cards will be a small size but they simply enter in a large size for the partition table in hopes of tricking the device and computer into thinking it is a large drive but when you exceed the true storage of the drive, all new data simply randomly overwrites random cells of data in the drive causing the data to corrupt.

also counterfeit sd cards have gotten better at looking genuine. when I purchased a 4GB sandisk ultra from the marketplace, I got a fake card, when I sent pictures to sandisk (since the seller refused to take them back and give me a refund because they insisted they were genuine, I sent them off to sandisk and only upon taking it apart and testing the individual chips 9which also had the sandisk logo and model numbers, did they find out that they were not genuine and then I was able to get a refund. Criminals are getting better at making real looking fakes. When ever you buy a sd card, look at reviews to find out it's true read and write speeds, then benchmark the card you purchased.

anyway, to reformat your sd card, you first need at least a 1GB flash drive. install ubuntu to the flash drive, then boot into it

after that, using gparted in ubuntu, reformat your flash drive.
