I've attached a patch which re-adds the check for gptmbr.bin and
found, then the script will now automatically grab the partition's unique
UUID and write a compatible MBR. It should work on all drives with an LBA
size of 512 bytes.
The patch also includes a minor fix: If --format is specified and the
user has accepted the first warning by hitting <enter>, then it will
automatically unmount all partitions on the device so that the parted
commands don't fail.
