Abstract: Embodiments described herein provide an apparatus that is operable with a storage system. The storage system includes a controller operable to assign a pointer to a first track of a magnetic disk when data is written to the first track. The pointer points to the end of the data in the first track. The controller is also operable to detect a successive write to an earlier written portion of the first track, to update a location of the pointer based on the successive write to the earlier written portion of the first track, to increment a write count of the first track based on the successive write to the earlier written portion of the first track, and to rewrite a track adjacent to the first track when the write count breaches a threshold number.

Abstract: Embodiments described herein provide an apparatus that is operable with a disk drive. The apparatus includes a memory device operable to store a plurality of bit sets. Each bit set identifies a track and a sector of the disk drive and a number of times that the track of the disk drive has been written. A controller of the disk drive is operable to increment the number when the track is written. Each bit set comprises a number of bits that is established according to track location of the disk drive.
