System and method for hiding P-list entries for a disk from an initiator using a small computer system interface

摘要

A disk drive provides a defect list for each recording surface itemizing selected areas of recording surface by location, size and graded by an expected abnormal error rate. The defect list is utilized upon formatting of a recording surface to rate sectors as available or unavailable depending upon a map of data types to be written to the sectors and alignment of the map to the defects.
