Ubuntu 13.04 至 13.10 升级导致驱动器无法访问

我最近从 13.04 升级到 13.10，在重新启动系统时遇到内核崩溃。我的驱动器上有一些未提交的代码，所以我打算使用实时 USB 将其取出，但不幸的是，当我尝试打开驱动器时出现此错误。

在此处输入图片描述

Here it the output for dmesg | tail

这是 fdisk -l 的输出

有什么办法可以将我未提交的代码从驱动器中取出吗？

答案1

从现场 DVD 中执行sudo e2fsck -c /dev/sda6（在确认之前先查看问题的答案，但对所有问题回答是应该安全的）。

之后检查sudo e2fsck -c -c -p -v /dev/sda6磁盘是否报告了合理的结果。警告：此命令将需要一些时间！
