The problem on the usb i that it runs the checksum on the whole >
usba including all those 0 at the ned. thus youmust use the actual size
of the image
dd if=/dev/sdc bs=<N> count=<M> |md5sum

where the numbers <N> and <M> are replaced by two numbers whose product
exactly equals the length of the iso file written to the USB. That sdc
should be replaced by the full disk name of the usb witout a partition
number.

"it" means what?
