System and method for disk sector failure prediction

摘要

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.

主权项

1. A system for predicting sector failure on a magnetic storage disk, comprising:
at least one processor and a memory storing computer-readable instructions that, when executed by the at least one processor, causes the system to at least: access data located at individual sectors within a plurality of sectors; and determine a likelihood of failure of a first sector of the plurality of sectors without accessing data located at the first sector, the likelihood determined based at least in part upon access of a head to a second sector within the plurality of sectors, failures in the second sector, and relative locations of the first and second sectors on the at least one magnetic storage disk.
