The storage system includes a data dividing means for dividing writing target data into a plurality of units of partial data, and generating units of new divided file data; an index file generation means for generating, for each of the units of partial data, an index entry, and generating index file data by adding test data for error detection; a data writing means for writing the divided file data and the index file data; and a recovery means for detecting an error in the index entries written in the storage device, based on the test data included in each of the index entries. The recovery means deletes an index entry in which an error is detected and all of the subsequent index entries in the index file data stored in the storage device, from the index file data. |
