Read-only当我的硬盘工作量很大时，我的 ubuntu 就变成了这样！例如，在下载大文件（超过 1GB）或full-upgrading使用 apt（约 400MB）后，我无法打开任何桌面应用程序，甚至无法tab-completion在终端中使用！解决方案是重新启动笔记本电脑，当initramfs页面出现时运行以下命令：
fsck.ext4 /dev/sda7
(and press "a" to answer "inodes that were part of a corrupted orphan linked list found")
/dev/sda7我的分区在哪里/home？我将文件下载到了这个分区。
运行此命令后，我的 ubutnu 再次启动，但当硬盘工作很多时，问题又出现了！问题是什么？是我的硬盘问题还是软件问题？我该如何解决这个问题？提前致谢。
