Abstract
A hard disk drive (HDD) controller comprises a channel module and a control module. The channel module reads and writes data to a magnetic medium. The control module defines non-overlapping first and second areas of the magnetic medium, receives a write request containing first data for a first address in the first area, and caches the first data at a second address in the second area before storing the first data at the first address.
