Abstract
A storage device and method for updating a shadow master boot record (MBR) are provided. In one embodiment, a storage device is provided having a memory with a first storage area and a second storage area. The storage device receives updated sectors of the shadow MBR from a host device and writes the updated sectors in the second storage area. The storage device determines a highest written sector in the first storage area that is occupied by the shadow MBR. The storage device copies the non-updated sectors of the shadow MBR from the first storage area to the second storage area, wherein only the non-updated sectors up to the highest written sector are copied. Accordingly, any non-updated sectors above the highest written sector are not copied from the first storage area to the second storage area. The storage device then designates the second storage area as storing a current version of the shadow MBR.
