Claim Text:
1. A disk-error detection system comprising: a storage array including a plurality of storage disks configured to store data; a processor in communication with the storage disks, wherein the processor is configured to: detect presence of an initial media error in a storage disk from the plurality of storage disks during a read operation of the data stored on the storage disk; perform an initial media-error detection scan of a portion of the storage disk over a predetermined portion size of the storage disk in response to the detection of the initial media error, wherein location on the storage disk of the portion of the storage disk is based on location of the initial media error on the storage disk; and perform an additional media-error detection scan each time at least one media-error is detected in a prior media-error detection scan, wherein each additional media-error detection scan is configured to cover a respective unscanned portion of the storage disk, wherein location of each respective unscanned portion of the storage disk is based on location of a single media-error detected during the prior media error detection scan.
