This is a bit of a mess, as you should NEVER EVER have anything
other than a "GPT Protective MBR" in the MBR on a disk that has a
GPT. This is basically mixing two very different partitioning
schemes on the same disk (that can only lead to sadness).

The tools won't replicate this, nor should they, as it is a
seriously broken setup. To fix this setup, delete MBR parition 0.
