摘要:
A system and method to avoid disk lube pooling is presented. A track access monitor tracks the number of times that a program accesses a particular track located on a hard drive. When the track access monitor determines that the number of track accesses to a particular track exceed a track access threshold, the track access monitor invokes a sequence of events to scan adjacent tracks in order to uniformly redistribute lubrication over the hard drive. In one embodiment, the track access monitor incrementally performs the adjacent track scanning during hard drive idle periods, such as when the system waits for a password from a user or when the operating system conserves power and idles the hard drive due to lack of activity.
