Abstract
A storage device is disclosed comprising control circuitry. A write command is received from a host, wherein the write command comprises a host block and corresponding host block address. The host block is partitioned into a plurality of sub blocks, and a plurality of sub block addresses are generated in response to the host block address, wherein each sub block address corresponds to one of the sub blocks. Error detection code (EDC) data is generated for each sub block in response to the sub block and corresponding sub block address. Each sub block and corresponding EDC data are combined to generate a plurality of partial codewords that are written to one or more data sectors corresponding to the sub block addresses.
