我聪明地运行，发现了一些奇怪的错误，尽管磁盘很新 Power_On_Minutes 427h+41m
我很好奇，这些是以前硬盘的错误吗？
Error 1 occurred at disk power-on lifetime: 13729 hours (572 days + 1 hours)
When the command that caused the error occurred, the device was active or idle
Error 2 occurred at disk power-on lifetime: 23300 hours (970 days + 20 hours)
When the command that caused the error occurred, the device was active or idle.
输出如下

这个硬盘是否很快就会出现故障并需要更换？
答案1
当您轮询 SMART 数据时，您不是从某个缓存中获取数据，而是直接从驱动器中获取数据。它永远不会显示旧驱动器的结果。在这种情况下，您的驱动器出现故障，是时候将其丢弃了。
答案2
另一方面，我没有看到任何迹象表明磁盘正在损坏。计数器中没有常见的磁盘损坏症状，例如：
Reallocated_Event_Count - 0Current_Pending_Sector - 0Offline_Uncorrectable - 0
但你看到的却是这样的：
UDMA_CRC_Error_Count - 2
我不会为此烦恼。循环冗余校验CRC 是一种在数据发送后进行验证和更正的方法。此警告告诉您，驱动器发送/接收的数据在某一时刻未通过此检查。最常见的原因是电缆或磁盘控制器故障。噪音或电阻可能会导致某个位翻转。
