A computer is operable to store a set of encoded data slices of a data segment, where each encoded data slice includes a corresponding checksum of a plurality of checksums. Based on ones of the plurality of checksums corresponding to the set of encoded data slices, it is determined when the set of encoded data slices includes at least one corrupted encoded data slice. At least a threshold number of encoded data slices of the set of encoded data slices are retrieved, and a reconstructed data segment is generated using the at least the number of encoded data slices of the set of encoded data slices. At least one at least one reconstructed encoded data slice is formed utilizing the error correcting information dispersal algorithm on the reconstructed data segment, and the at least one corrupted encoded data slice is replaced with the at least one reconstructed encoded data slice.
