Method and apparatus for time correlating deffects found on hard disks

摘要

A hard disk drive system (50) is configured with logic that time correlates grown defects. The hard disk drive system (50) time correlates grown defects by associating each occurrence of a grown defect with a time stamp. When the hard disk drive system (50) receives a read defect data command sent by the host processor (30), the hard disk drive system (50) returns time correlated grown defect information to the host processor (30). The host processor (30) preferably executes a software program that processes the time correlated grown defect information to determine any changes in the number of grown defects that are occurring as a function of time.
