У меня двойная загрузка на моей машине: Windows 8 и Ubuntu 11.10.
Внезапно один из моих разделов испортился.
На Windows это показывает эту ошибку.
Местоположение не доступно.
E:/ не доступен.
Файл или каталог поврежден и не читается.
Вот снимок Disk Management в моей бета-версии для Windows 8.
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)
На Ubuntu,
Когда я пытаюсь смонтировать раздел через nautilus, я получаю
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
dmesg | tail or so

Запуск fdisk показывает это:
jatin@silverSpoon:~$ fdisk /dev/sda -l
Cannot open /dev/sda
Запуск fsck, показывает это:
