Abstract
A posted-write queuing program for writing information sectors to disk sectors includes error-handling routines to minimize the risk of data loss upon specified types of errors. Upon timeouts, queuing is suspended and all information sectors pending in the queue are written out to the corresponding disk sectors. Upon specified types of write errors, queuing is discontinued and repeated attempts are made to write out all information sectors to the corresponding disk sectors. For each unsuccessful attempt, the corresponding information sector is saved in the queue; the user is alerted, and subsequent read or write requests directed to the corresponding disk sector is serviced from the saved information sector in the queue.
