Abstract
A storage system is described that includes a controller and a disk array. The controller operates to coordinate data transfers between the disk array and an external host computer in response to I/O commands received from the host computer. The controller further operates to execute a background program each time certain conditions are met. Under the direction of the background program, the controller operates to identify corrupt but readable data blocks based upon the value of the data block and the value of an error code stored for the data block.
