Abstract
A method begins by a dispersed storage (DS) processing module of a storage device receiving an encoded data slice of a set of encoded data slices, where the set of encoded data slices has associated therewith a set of integrity values, and where integrity information is generated from the set of integrity values. The method continues with the DS processing module generating an integrity value for the encoded data slice and obtaining at least a portion of the integrity information from another storage device. The method continues with the DS processing module generating a comparative integrity value for the encoded data slice based on the at least a portion of the integrity information and facilitating storage of the encoded data slice in memory of the storage device when the integrity value compares favorably to the comparative integrity value.
