Abstract:
A data write control method for writing data onto a disk in response to a write request, comprising:storing data requested to be written from the write request in a storage area before writing; reading data from at least a succeeding sector located next to a last sector in sectors targeted for writing when the write request does not contain a designation for a last sector of a track on the disk; writing data requested to be written from the write request onto the disk; reading out the written data from the disk; comparing the written data read out from the disk with the data stored in the storage area so as to determine whether or not the data written onto the disk has been successfully written; reading out the data from the succeeding sector of the disk; and comparing the data read out from the succeeding sector after the writing with the data read out from the succeeding sector before the writing so as to determine whether or not the data in the succeeding sector has been destroyed.
