Abstract
Systems, methods, and software are provided herein for error correction in writing and reading data to and from a data storage device. In one implementation, an encoder matrix is used to generate, for a data set, first error correcting code (ECC) parity data on a host system, and second ECC parity data for tracks on data storage device coupled to the host system. Once generated, the data storage device will store the data set and the first and second ECC parity data on storage media for the device. When a read is required, the storage device will provide a first version of the data set with the first and second ECC parity data to the host system, permitting the host system to use the parity data to generate a corrected version of the data set.
