每当我启动计算机时,正常的启动过程几乎总会短暂中断。黑色背景上带有白色文字,显示的内容大致如下:
/dev/sda2 clean: <number>/<bigger number> blocks
或者,也许更可怕:
/dev/sda2 clean: <number>/<bigger number> blocks <number>/<bigger number> <number>/<bigger number>
诸如此类。我的问题是:我的硬盘是不是要坏了?
答案1
答案2
正如链接的答案所述,fsck
应该偶尔运行,但不能“几乎总是”就像你的情况一样。要查看运行频率,请使用:

但在您的情况下,请将sdc3
示例中的 替换为sda2
。
在此示例中,fsck
每次启动时都会运行。
fsck
要更改磁盘运行的频率,请使用:
$ sudo tune2fs -c 50 -i 1m /dev/sda2
这会将运行频率设置为每 50 次启动或每月一次。
现在你应该看到:
