what about a binary diff on those two written images. i guess the difference should be at the beginning / end of the device. just diff their hex value instead of a real binary diff. try
$ dd if=/dev/sda bs=1024 count=1 | hexdump -x > outfile or $ dd if=/dev/sda bs=1024 skip=30719 count=1 | hexdump -x > outfile (31457280=1024*30720) diff those outfiles and hopefully we can see what's happenning with different dd builds.
