Abstract
A data storage device is disclosed comprising a non-volatile memory including a plurality of memory segments. A write command is received comprising a logical block address (LBA) and user data. The LBA is mapped to a physical block address (PBA) for addressing one of the memory segments. First error code redundancy is generated in response to the LBA, and second error code redundancy in response to the PBA. User data and the first and second error code redundancy are written to the memory segment addressed by the PBA.
