Abstract
A storage device includes a controller configured to adjusts direct offline scan (DOS) parameters for a scan of a storage region based on a workload affecting the storage region to mitigate data loss due to adjacent track interference (ATI) while also mitigating performance delays due to DOS execution. In one implementation, a type of workload occurring in a region is determined by assessing a distribution of write track counter values corresponding to data tracks in the region.
