1. A method for execution by a processing nodule of a computing device, the method comprises: sending list digest requests to storage units that, collectively stored data as a plurality of sets of encoded data slices, wherein a list digest request of the list digest requests is requesting a representation of a slice name information list regarding encoded data slices of the plurality of sets of encoded data slices stored by one of the storage units; interpreting list digest responses from at least some of the storage units to identify an inconsistency between at least two of the list digest responses, wherein a list digest response of the list digest responses includes the representation of the slice name information list regarding encoded data slices of the plurality of sets of encoded data slices stored by the one of the storage units; when the inconsistency exists between the at least two of the list digest responses, executing a process to identify one or more encoded data slices of the plurality of sets of encoded data slices having a slice storage error; and initiating an error correction process for the one or more encoded data slices having the slice storage error.
