In this example the offset is provided by the loop devices. If you don't like loop devices you can use seek=X skip=X (same X) but you should triple check the offset is correct, data at this offset should be identical on both arrays. (What my example checks using `cmp` which should return differ at byte xxxxxxxxx. Have a look at it with hexdump too so it's not just zeroes...) Regards Andreas Klauer
