Did you try another USB stick? I had cases when there were no errors during write but USB stick happily returned zeroes for the half of its capacity.

I've heard about fraudulent high-capacity USB sticks that
can be purchased on Amazon. Make sure you purchase
name-brand sticks, they may cost more and be of lower
capacity, but you won't get ripped off!
