Abstract: Apparatus and method for recovering errors from erroneous files in a storage system. In order to recover the errors from the erroneous files, each of at least three erroneous files stored in the storage system may be divided in half to form three sets of divided files. Three corresponding, portions from each of the three sets of divided files may be compared. A determination may be made as to whether at least two portions among the three corresponding portions are substantially identical. Based on the determination, substantially identical portions are determined to be non-erroneous portions. Then, a non-matched portion that is not substantially identical to the two substantially identical portions may be replaced with one of the non-erroneous portions.
