Abstract: A disk-error detection system may include a storage array having a plurality of storage disks configured to store data. The disk-error detection system may include a processor in communication with the storage disks. The processor may detect presence of a media error in a storage disk from the plurality of storage disks during a read operation of the data stored on the storage disk. The processor may perform a media-error detection scan of a predetermined portion of the storage disk in response to the detection of the media error. The location on the storage disk of the predetermined portion of the storage disk may be based on location of the media error on the storage disk. A method and computer-readable medium may also implement disk-error detection.
