我最初在 openmediavault 社区论坛上发布了此消息，但从未收到回复。我希望对 SMART 有所了解
我购买了此驱动器亚马逊一切似乎都运行良好，所以我又买了一个，所以我有两个完全相同的型号，但是第一个开始显示坏扇区。我知道这是一个经常讨论的话题，我很抱歉又有一个偏执的人担心他的驱动器，但人们会对他们的驱动器产生偏执，我就是其中之一。
我从 openmediavault 的 GUI 中设置了智能，并设置了每月一次的一些计划（顺便问一下，这样可以吗，或者是建议进行智能计划）我订购的第二块硬盘运行良好，运行 OMV OS 的 SSD 也是如此。
当我收到第一封来自 smart 的电子邮件时，说我有 24 个当前无法读取（待处理）的扇区，这让我很担心，我确实读了很多资料，并且有点明白，如果我是对的，它正在等待读取这些扇区并删除可以替换和放置坏扇区的数据。我可能大错特错。这是我每天的电子邮件 我收到的电子邮件的屏幕截图 重启后我收到了这个。2 个离线无法纠正的扇区 有人可以向我解释一下 Reallocated_Sector_Ct 吗？SMART信息属性截图还剩下一个问题，寿命？自检日志 如果我执行 smartctl -x，那就是我的信息。如有任何帮助或见解，我们将不胜感激。
