Abstract
A disk drive is disclosed comprising a head actuated over a disk comprising a plurality of data tracks. A first defect shape is detected during a manufacturing defect scan of the disk. A second defect shape is detected while the disk drive is deployed in-the-field. Whether the first defect shape is connectable to the second defect shape is determined, and when the first defect shape is connectable to the second defect shape, data sectors along a trajectory between the first defect shape and the second defect shape are relocated.
