Abstract:
A storage device includes a data degradation management module that tracks a risk of data degradation by incrementing a track write counter of a first data track responsive to each data write command to a second data track, such as a data track directly adjacent to the first data track. If a count of the track write counter exceeds a count threshold, one or more post-write scan operations are performed to assess and/or repair data degradation of the first data track.
