Abstract
Apparatus and methods for managing data stored in a disk drive having at least one disk including a first zone of tracks for storing data and a second zone of tracks for storing data, with the second zone being adjacent the first zone. It is determined whether a write counter for the first zone exceeds a threshold value. The write counter for the first zone represents a number of times the first zone has been completely written with data. If it is determined that the write counter for the first zone exceeds the threshold value, the disk drive is controlled to rewrite data from at least a portion of the second zone.
