Abstract
A method and system are disclosed for recovering lost data with redundancy in an individual hard drive. A mirroring-type process is used in a single hard drive to maintain a backup copy of all data stored on that hard drive. The hard drive maintains two copies of the stored data on different storage media segments or partitions defined by separate read/write heads. In the event that a hard drive media defect or error occurs with respect to any of the data stored on a segment defined by one head, that data can be restored from the segment defined by the other head(s).
