SMART HDD 状态输出解释-感谢帮助

SMART HDD 状态输出解释-感谢帮助

这是 ubuntu 系统上出现一些奇怪安装错误的磁盘。我不确定这是由于 fstab 中的错误设置还是实际的硬件错误造成的。我运行 smartctl 来检查磁盘的状态。我没有读取结果的经验,但对我来说,该磁盘似乎存在严重问题。但购买磁盘的商店里的人说,磁盘没问题。有没有人有空给我提示一下磁盘的实际状态以及 SMART 结果有多重要?

答案1

参数值标准化为 100,越低表示越差,如果低于指示的阈值,则标记为失败。

您有一个显著的原始读取错误率,并且硬盘已经为此目的重新分配了所有备用块。

所以磁盘不管出于什么原因都坏了。你也许还能读取所有内容(也许店里的人已经测试过了),但可能不能持续太久。

尽快进行备份,以免为时已晚,并获取新磁盘。

编辑

对于备份,请确保以只读方式安装驱动器。超级块在安装期间被标记,如果驱动器无法写入它并尝试分配它,并且没有任何备用块可以分配,则会出现问题 - 这可能会给您带来您提到的“奇怪的安装错误”。

(是的,我知道您已经做了备份,但将来可能会有其他人读到这篇文章)。
