ls: reading directory .: Input/output error
提问by Vimos
My system raised the I/O error when I tried to use 'ls' on a mounted hard disk.
当我尝试在已安装的硬盘上使用“ls”时，我的系统引发了 I/O 错误。

This sort of thing is indicative of an impending hardware failure. I'd do what you can to back up everything you need to somewhere else and replace the drive before it fails irreparably.
这种事情表明即将发生硬件故障。我会尽您所能将您需要的所有内容备份到其他地方，并在驱动器出现无法修复的故障之前更换驱动器。
