我的机器上有双启动：Windows 8 和 Ubuntu 11.10。
突然，我的一个分区损坏了。
在 Windows 上，显示此错误。
位置不可用。E
:/ 不可用。
文件或目录已损坏且无法读取。
Disk Management这是我的 Windows 8 开发者测试版 的快照。
Here, I have:
The first partition: ext4 filesystem: ubuntu 11.10
The second partition: swap
The third partition: Has my precious data(***NOT WORKIING, type auto-changed from NTFS to RAW***)
The fourth partition: Has data too, and working
The fifth partition: The Windows partition(Windows is installed on this one)
在 Ubuntu 上，
当我尝试通过 nautilus 安装分区时，我得到了
Error mounting: mount: wrong fs type, bad option, bad superblock on /dev/sda2,
missing codepage or helper program, or other error
In some cases useful info is found in syslog - try
