ABSTRACT:
An apparatus, system, and method are disclosed for hard disk drive redundancy. A demarcation module demarks a parity data block in each set of a specified number of data blocks on a hard disk drive. An association module associates a PBA of each un-demarked data block with a LBA. A write module writes the data to the un-demarked data blocks. A parity module calculates parity data for the data written to the un-demarked data blocks and the write module writes the parity data to the parity data block.
