A disk drive operative to reduce squeeze hard error is described. In response to a write fault (404) indicating that data has been inadvertently written to some portion of a track adjacent to an intended track, track overshoot is determined (416) based on a position error signal (PES) and pre-stored head width data. If the track overshoot exceeds a threshold (418), data from the adjacent track is read and rewritten (422) to remove the overshoot interference. Preferably, the reading and rewriting is performed during an idle mode immediately following the write fault using previously stored addresses.
