上网本有一个 system-lubuntu 18.04.5 64 位。如果突然关闭电源、按键关闭或其他不可抗力，当上网本不是通过“关机”关闭时，系统启动时会出现错误“/dev/sda1: UNEXPECTED INCONSISTENCY;”。意外的不一致屏幕
我写 fsck /dev/sda1，结果是“写入文件系统信息时出错：输入/输出错误”。输入输出错误画面
上网本仅用于访问网络。磁盘上没有有价值的数据，除了设置和 chrome 浏览器。问题：如何使一切正常，也许有一些命令可以修复错误，因为磁盘上没有任何有价值的东西（理想情况下，保存设置和chrome），以免重新安装系统？或者您可以为旧/弱 PC 推荐更稳定的操作系统（上网本：CPU Intel Atom N450 1.66 ghz，1gb RAM，250gb）？
