Check if original and duplicated offsets refer to the same cluster.
Repair the image and check that writing to a referred cluster
doesn't affects another referred cluster.

Maybe, add also read -P 0x55 for 4th cluster, to be sure that it's really
unchanged.
And maybe read 0x11 for 0th cluster, to be sure that it's really rewritten.
