What method are you using to compare the files?

What happens when you copy:
a) between two different USB devices
b) from hard-disk to USB stick and then back to hard-disk?

The amount of disk space used will probably be different in different 
media because of differences in the format system and/or block size.

But it's almost certain that the actual *contents* of the files - as 
seen by the applications which use those files - will be the same.

I suspect that you are chasing a non-existent problem.
