Michael, I think we agree, but do remember that the 'lifetime of the disk' is the real question here, and the whole reason we are doing mirroring anyway. When the disk fails and is swapped out with a replacement, the MBR also has to be rewritten then, and we want that to be as automatic as possible.

But it is necessary to set it up only once on every disk, and forgot about it. "Standard" MBR that comes with MS-DOS, or any other similar MBR code will work, and there's no reason to touch it during the whole lifetime of the disk.
