Abstract
A method, computer program product, and computing system for sensing the occurrence of an uncorrectable condition within a data stripe of a RAID array. The data strip includes a plurality of data portions and a parity portion. One or more invalid data portions included within the plurality of data portions are identified. The one or more invalid data portions are populated with filler data having a known pattern, thus defining one or more filler portions. The parity portion is updated based, at least in part, upon the one or more filler portions, thus defining an updated data stripe that includes an updated parity portion.
