USB Takes long time to unmount

[Matt Patterson]

I would much rather have a realistic measurement of the drives speed so 
that when I am dropping files onto it and leaving I can predict when 
things will finish instead of waiting an unkown time for unmount ot happen.

Thanks for the tip, I will give it a try!
