当前待定扇区和脱机的原因不可纠正地增加然后减小到零


12

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驱动器的完整(当前)输出:

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。
斯文

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。
拉曼

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...

我最近使用类似的Seagate ST3000DM001-1CH166固件CC24进行了几次此操作。您不需要Seatools,只需运行长时间的智能测试即可:

smartctl -t long /dev/sdc

然后,如果smarctl没有显示任何错误,那么您现在可以:

SMART Self-test log structure revision number 1
Num  Test_Description    Status                  Remaining  LifeTime(hours)  LBA_of_first_error
# 1  Extended offline    Completed without error       00%      9912         -

如果失败,则直接发送回Seagate。他们在大约一周内更换了我上次失败的产品。


扩展的脱机自检完成,没有错误。

那些磁盘!他们似乎有40%的失败率。

当前的待处理扇区就是,磁盘知道的位置数需要重新分配,但尚未重新分配,因为磁盘没有要重新分配数据的源。一旦写入该位置,磁盘将自动将该区域重新分配到另一个位置,并将新数据写入新位置,并且当前待处理的扇区容量将减少。

一切都很好,磁盘应该如何运行。

您可以在Linux上使用diskscan或在Windows 上使用HD Tune扫描磁盘中的错误位置,也可以通过使软件写入位置来尝试“修复”这些位置,以便立即尝试重新分配。


1
谢谢,但我知道“当前待处理的部门”的含义。在我的问题中,您会看到我特别指出重新分配计数仍为零。您对减少未决扇区数而没有相应增加重新分配数有任何解释吗?请注意,我运行的所有磁盘测试都很好,并且磁盘仍然嗡嗡作响,没有明显的问题。
拉曼

2
磁盘可能有一个无法读取的扇区,因此有一个待处理的扇区,当需要在该位置进行写操作时,磁盘可以测试该位置并查看写操作是否成功,从而取消了重新分配,这说明了计数器降至零,但没有添加任何重新分配。
Baruch Even

好的,这对于当前待处理的部门是有意义的。但是,Uncrorrectable脱机如何能从10变为0?难道“不可破解”意味着它们永远消失了,并且将永远保持离线状态吗?
JustAMartin 2015年

在Ubuntu上,只需从而不是从github安装即可sudo apt-get install diskscan。(我猜你是两个版本的作者。)
