No, No, NO. The MBR is only the first 446 bytes of block 0. The rest is
the partition table. I assume you don't want to rewrite the partition
table.


Quite. So you save the partition table separately:

No. The PT is a part of the MBR, which should be saved
as a whole. If one later decides not to replace the PT
portion of them MBR when "undoing" an operation, that
decision should be made then, not when doing the save.
