Abstract: A method and system for preserving data of a storage device are disclosed. In one embodiment, the method includes determining a number of times data is written to a first track in a first region of a storage medium, and rewriting data from a second track that is adjacent to the first track in the first region if the number of times data is written to the first track in the first region exceeds a first predetermined threshold. The method further includes determining a number of times data is rewritten to the second track in the first region, and relocating data from the second track in the first region to a second region of the storage medium if the number of times data is rewritten to the second track in the first region exceeds a second predetermined threshold.
