XP has a built in tool called DISKPART. Use it on your USB stick to reformat it. http://support.microsoft.com/kb/300415 !!!!Note it will completely wipe all information from the disk!!!!

I had the same problem with an SD card a couple of years ago. I was copying an 800MB WAV file to a 2GB SD card that already had around a gig of stuff on it. When the card hit 80% of its capacity, the copying stopped, and all of the data on the card was destroyed. I had to reformat that cheap piece of crap in my camera, since Explorer would freeze if I tried to access it. After a few months of additional usage, I could only use 1.2GB before the data corruption would occur. You should buy a new card for your camera before it gets any worse. The flash chips in those memory cards don't last forever.
