Abstract
Aspects of the invention include a method and apparatus to defragment data on a disc drive storage system by optimizing the available physical block address on a media into one or more contiguous physical block addresses then storing the fragmented data into the one or more contiguous block address. In one aspect, the disc drive uses a reserved area on the media to hold fragmented files during the defragmentation process. In another aspect, sectors of the media having faster access time are used to store defragmented files that have a higher incidence of access relative to other files on the media.
