每分钟 2000 万次 Raw_Read_Error_Rate

Que*_*ark 1 hard-drive smart hp-pavilion laptop-repair

我决定检查我的硬盘驱动器的 SMART 状态,我看到它有125239624原始读取错误。一分钟后,我再次检查以进行比较,这取决于127315512原始读取错误。

我应该担心吗?此驱动器可能仍在保修期内。我应该送去修理吗?

这是完整的输出smartctl -data -a /dev/sda

由于这个原因,SMART 结果格式有点垃圾(好吧,至少它令人困惑)。现代磁盘充满了数据,原始错误率通常相当高 - 在应用纠错后,数据访问/可靠性不会出现问题。

我会关注以下几点:

196 Reallocated_Event_Count 0x0032 100 100 000 Old_age Always -0 197 Current_Pending_Sector 0x0032 100 100 000 Old_age Always -0 198 Offline_Uncorrectable 0x0030 100 100 000 Old_age Offline -0

这是重新分配等待重新分配无法重新分配的扇区数。

当磁头碰到坏扇区而读取失败时,它变成了一个Current_Pending_Sector. 下次尝试写入时,它要么工作(一切恢复正常,扇区被重新分配)要么再次失败——如果池中有可用的重新分配空间,它将被重新分配。( Reallocated_Event_Count+1)。如果池用完,则扇区变为Offline_Uncorrectable无法再进行读/写。

由于您的驱动器没有任何扇区问题,只有标准、现代、数据密度Raw_Read Error_Rate,我认为您很好。关于备份的标准建议始终适用,但我认为在这里并不比在任何其他情况下更适用。
