Abstract

A data storage device is disclosed comprising a non-volatile memory comprising a plurality of sectors. At least one alignment zone is defined in the non-volatile memory comprising a plurality of chunks including a plurality of data chunks and a plurality of pad chunks, wherein each chunk comprises a plurality of sectors. Each sector is operable to store X host blocks, the alignment zone comprises at least X−1 pad chunks, and control circuitry is operable to shift the data chunks of the alignment zone by a number of chunks equal to or less than X−1 plus a corresponding offset.
