Abstract
An apparatus, system, and method are disclosed for managing data storage. The method includes determining that an error correcting code (ECC) block comprises uncorrectable errors. The ECC block is stored across a plurality of memory devices. The method includes iteratively substituting replacement data, within data of the ECC block, for individual memory devices of the plurality of memory devices to form substitute ECC blocks until one of the substitute ECC blocks is correctable using the error correcting code for the ECC block. The method includes providing corrected data from the correctable one of the substitute ECC blocks.
