description A system and method for predicting the likelihood of failure of the individual sectors of a magnetic storage disk based upon the monitoring of adjacent sector performance in responding to access requests. The prediction for a specific target sector's fidelity can be made through the gathering of sector performance data that occurs during normal read/write actions to the adjacent sectors, without a recent access request necessarily being made to the target sector. Scrubbing of the sectors can also be directed based upon the needed sector access data for target sector fidelity prediction.
