Flashdrive says it full when it empty...??? help

I recently received an 8gb flashdrive and I synced it to my xbox. Afterwards I tried to put material on it and it kept telling me that the disk was full when I hadn’t put anything on it. Please help

I am having the exact same problem after using my 16gb drive to save Gears of war 3 data…

Have you written to Xbox about the situation?  It was the last to touch the drive before the problem occurred.  Maybe Xbox is formating it to a file system that Windows can’t read.
