摘要

本文提出了一种新的改进方法，用于检测磁盘存储介质劣化引起的磁盘子系统扇区潜在故障。如果在很少访问的扇区出现介质劣化，可能会导致硬盘的潜在故障长时间不被发现。提出了一种利用磁盘空闲时间扫描常用SCSI磁盘的自适应算法。

Detecting latent sector faults in modern SCSI disks

The authors present new improved methods for detecting latent sector faults in a disk subsystem as caused by media deterioration of the disk magnetic storage material. In case of media deterioration on the rarely accessed sectors, a latent disk fault may remain undetected for a long time. An adaptive algorithm is proposed to utilize the idle time of the disk for scanning commonly used SCSI disks.<>
