摘要：
The input/output (I/O) performance of a hard disk drive in a mass storage computer system is evaluated to maintain efficiency by addressing I/O commands to sectors of the disk drive, evaluating the execution of the I/O commands to the sectors to obtain performance information for the sectors to which the I/O commands are addressed, comparing the performance information to a predetermined I/O performance criterion, and identifying any impaired sectors in which the performance information indicates less than the predetermined I/O performance criterion. Thereafter, further I/O commands to the impaired sectors are avoided.
