That doesn't make U3 as useful as it sounds.  I bought a flash drive 
with Gatesware backup software on a U3 partition and found that, 
although Fedora could see the partition, it couldn't mount it or do 
anything with it.  It was just a waste of space.  I ended up putting it 
on a friend's Windows box to run the removal program to recover the space.
