linux – 我应该关注SMART Hardware_ECC_Recovered值高吗？

我在/ var / log / messages中收到了这样的消息：

Jun 25 06:29:27 server.ru smartd[4477]: Device: /dev/sda,SMART Usage Attribute: 195 Hardware_ECC_Recovered changed from 46 to 47

这是否意味着磁盘出现故障,我必须更换它？我在哪里可以阅读有关S.M.A.R.T测试结果的解释？

解决方法

根据史蒂夫·吉布森(Steve Gibson)的名声,Spinrite名称,SMART值必须随着时间的推移而不是瞬时读数.这意味着,如果值为47个月,则值47不一定是坏的.然而,如果该值在一小时前是42,并且其快速攀升,那么这意味着驱动器在访问部分数据时遇到困难,并且可能很快就无法读取该扇区.根据该驱动器上的数据值,您可能希望替换它.
