在一周的过程中,对于3TB希捷驱动器(ST3000DM001-1CH166),smartd报告了脱机不可校正和当前不可读取(待处理)扇区的数量缓慢增加,然后逐渐减少,直到最终计数为0和错误情况重启。从日志中(仅显示更改):

此外,重新分配的扇区数也为0,因此这些扇区似乎没有被重新映射。这是smartctl -a

我已经下载了但尚未在驱动器上运行Seatools,但是驱动器的当前SMART状态基本上看起来不错。什么会导致这种行为?
更新:对于未来的读者,该驱动器实际上还可以使用几个月,这时更多的扇区变得不可校正/脱机,并且重新分配的扇区数开始增加到0以上,并且SMART长时间自检由于读取失败而开始错误。因此,这些消息似乎是有用的预警。
问题是:您信任此磁盘吗?我不会并且尽快更换它。

SMART可以是...有时候不聪明?我不信任任何数据的磁盘。从通电时间的外观来看,该驱动器已经使用了8个月了……您是否有保修?
—
内森·C
是的,它在保修期内。根据Seagate的保修信息,下一步是在其上运行Seatools。

更新:几个月后,驱动器自检现在失败,并且重新分配的扇区正在增加。我将退还驱动器以进行保修更换。

今天,我的希捷硬盘也发生了同样的事情。复制大文件时出现读取错误,因此我查看了SMART数据,发现重新分配的扇区数= 8,当前的待处理扇区= 10,脱机的不可复制= 10。然后,我运行了完整格式。之后,我看到“重新分配的扇区数”为8,但“当前待处理的扇区”为0-因此,如果没有待处理的扇区并且“重新分配的扇区”没有上升,这意味着它们实际上还不错,对吗?但是我震惊地看到Offline Uncrorrectable = 0。完整格式后不可修复的扇区如何进行纠正,这是一个谜...
