WebFSCAN is a disk scheduling algorithm to determine the motion of the disk's arm and head in servicing read and write requests. It uses two sub-queues. During the scan, all of the requests are in the first queue and all new requests are put into the second queue.Thus, service of new requests is deferred until all of the old requests have been processed.
