No, that's not the problem, "gpt recover" expressly refuses to do
anything at all if the device contains a regular MBR (attempting to
avoid accidentally wiping out valid filesystems I presume). Since
zapping the MBR followed by a recover works, I think it probably advisable
to leave that protection as it is.
