最近我有一个fsck error on boot，我必须手动运行 fsck。所以，我这样做了，问题就消失了。之后我运行smartctl -a /dev/sda并看到以下属性
ID# ATTRIBUTE_NAME FLAG VALUE WORST THRESH TYPE UPDATED WHEN_FAILED RAW_VALUE
201 Lifetime_Remaining% 0x0023 100 100 005 Pre-fail Always - 6
什么意思？这是我应该担心的事情吗？
我搜索了其他类似的问题，但没有找到答案。我的操作系统是Ubuntu 20.04
这是 smartctl 输出

这表明您的驱动器根本没有磨损，并且还有 100% 的使用寿命。
当它下降到 5% 时，就该恐慌了。
