I've been victim to this:
-------------------
Unfortunately, many newer USB keys come with "U3" Windows software (badware?) 
preinstalled. Removing U3 is highly recommended, and will free up additional 
space on your USB key, as well as eliminate a source of potential conflicts.

Find a Windows machine, and try these programs to uninstall U3. Unfortunately, 
they are a bit flaky. If one does not work, try the other:

Too bad I don't have a windows machine.
