Abstract
A method for managing scratches on a disk of a hard disk drive is disclosed. By dividing the disk into a plurality of evaluation groups, testing each evaluation group for defects, calculating line equations based on the detected defects and determining whether the defects of the evaluation groups appreciably conform to their respective line equations, scratch fill operations may be appropriately performed using the line equations.
