Abstract
A method of operating a storage controller is provided. The method includes determining encoded data to be written to a storage media by applying at least an initial encoding comprising a first error correcting code type and a subsequent encoding comprising a second error correcting code type. The method further includes writing the encoded data to the storage media, and responsive to reading the encoded data from the storage media, processing the encoded data into primary decoded data using one or more primary decoders employing the second error correcting code type and detecting when data errors arise in the decoded data. The method also includes based at least on detecting one or more data errors in the decoded data, processing the encoded data into secondary decoded data using one or more secondary decoders employing the first error correcting code type.
