Caution: Try this at your own risk (I am not an expert, A Senior Member should Evaluate).
I have Windows Vista. I had 3 fake memory MP3 Camera, Video, etc. players. Sizes advertised were 4GB, 16GB, 32GB. All were fake.
The partition fixes would not work for me because of the methods could not find the USB memories and partition them. Linux can. I had tried all else many, many times.

Get free Puppy Linux (lupu-501.iso) a small sized Linux System file at
http://puppylinux.org/main/index.php?file=Download%20Latest%20Release.htm
With ImgBurn (free), make a bootable CD (Less than 300MB). Set your boot sequence for CD first. Puppy runs from your memory and does not require an install. I used Gparted (from Puppy Menu) to delete the main partition. Reformat with Vista or XP to the true memory size.
