Method and system for preserving data of a storage device

A system comprising:

• a storage medium comprising a target track and an adjacent track to the target track;
• and
• a controller configured to:
• determine a number of times data is written to the target track of the storage medium;
• rewrite data from the adjacent track if a number of times data is written to the target track exceeds a first predetermined threshold;
• determine a number of times data is rewritten to the adjacent track;
• copy data from the target track to a first storage location of a media cache if the number of times data is rewritten to the adjacent track exceeds a second predetermined threshold;
• write subsequent data designated for the target track to the first storage location of the media cache;
• and
• relocate data from the first storage location of the media cache to the target track if subsequent data designated for the target track has not been written to the first storage location of the media cache for a time period T that is greater than a time threshold.

A controller containing controller-executable instructions that, when executed by the controller operably connected to a storage device, cause the controller to:

• determine a number of times data is written to a target track of the storage device;
• rewrite data from an adjacent track to the target track if a number of times data is written to the target track exceeds a first predetermined threshold;
• determine a number of times data is rewritten to the adjacent track;
• copy data from the target track to a first storage location of a media cache if the number of times data is rewritten to the adjacent track exceeds a second predetermined threshold;
• write subsequent data designated for the target track to the first storage location of the media cache;
• relocate data from the first storage location of the media cache to the target track if subsequent data designated for the target track has not been written to the first storage location of the media cache for a time period T that is greater than a time threshold;
• and
• rewrite data to a second adjacent track to the target track if a number of times data is written to the target track exceeds a third predetermined threshold, the target track positioned between the adjacent track and the second adjacent track.
