Abstract
A method of aligning a partition of a data storage device to a boundary of a physical data sector is disclosed. The data storage device comprises a non-volatile memory comprising a plurality of physical data sectors, wherein each physical data sector comprises a plurality of logical data sectors. A partition map is read from the non-volatile memory, wherein the partition map identifies a partition comprising a number of logical data sectors. A number of logical data sectors in each physical data sector is determined. Whether at least part of the partition aligns with a boundary of a physical data sector is determined. When at least part of the partition does not align with a boundary of a physical data sector, at least part of the partition is moved to align at least part of the partition to a boundary of a physical data sector.
