Abstract
A storage device may detect errors during data transfer. Upon detection of one or more data transfer errors, for example, the storage device can begin to scan pages within a plurality of memory devices for uncorrectable error correction codes. Once scanned, a range of pages within the plurality of memory devices with uncorrectable error correction codes associated with a write abort error may be determined. The stage of multi-pass programming achieved on each page within that range is then established. Once calculated, the previously aborted multi-pass programming of each page within the range of pages can continue until completion. Upon completion, normal operations may continue without discarding physical data location.
