Abstract: A method begins by a processing module decoding a set of encoded data slices to produce a decoded data segment and determining whether the decoded data segment includes an error. When the decoded data segments includes the error, the processing module identifies one or more errant encoded data slices by decoding another set of encoded data slices to produce another decoded data segment. The method continues with the processing module determining whether the other decoded data segment includes the error. When the other decoded data segment does not include the error, the processing module identifies the one or more errant encoded data slices and corrects the one or more errant encoded data slices. When the other decoded data segment includes the error, the processing module repeats, for yet another set of encoded data slices, the decoding step, the determining step, and the identifying and correcting step or the repeating steps.
