The difficulty is that media often are willing to hand out more
bytes than were written when copying the ISO image to them.
Therefore you have to curb reading for checksumming to the size of the
ISO image.
See

which explains this for optical media like DVD+RW and also for USB sticks.


Have a nice day :)
