我让smartd定期检查我的硬盘驱动器。 最近我被通知了一个我的硬盘驱动器上短暂的自测失败。

我的驱动器在欺骗我吗？ （这是一个Western Digital RE4。）它不报告Current_Pending_Sector，Offline_Uncorrectable或Reallocated_Event_Count。 它在Raw_Read_Error_Rate处报告1，并为Multi_Zone_Error_Rate报告1，但现在返回0。
我将更换驱动器，但是我不确定是否应该过度假设扩展的离线自检是可靠的。
您的SMART状态现在是否报告重新分配的部门？ 你做了一个破坏性testing，写道。 当驱动器find不能写入的扇区时，它将重新分配它们。 关注这个SMART值的变化很重要。
通常，SMART通常不会看到错误，而不是错误。 自我testing和重新分配的部门是更可靠的参数，所以你的驱动器可能是“破坏”（在被“捣毁”的方式:)）。
