tune2fs: нет такого устройства или адреса при попытке открыть /dev/sda1?

Мой жесткий диск плохо работает:

Apr  3 20:44:30 207 kernel: Remounting filesystem read-only

/ dev / sda1 подключен к /data. Система выдает мне "Ошибка ввода / вывода", когда я cd в некоторые папки.

Я собираюсь бежать fsck на этом устройстве выполните следующие действия:

1. остановить доступ всех служб к / data
2. размонтировать / данные
3. tune2fs -O ^ has_journal / dev / sda1
4. e2fsck -fcy / dev / sda1
5. tune2fs -j / dev / sda1

но я получил следующее при выполнении шага 3:

# tune2fs -O ^has_journal /dev/sda1 
tune2fs 1.39 (29-May-2006)
tune2fs: No such device or address while trying to open /dev/sda1
Couldn't find valid filesystem superblock.

I backed up some parts of data on this. Что мне теперь делать?

P/S: This disk has been used about for 1 year. My system requires high read/write intensity, should I change to SSD?
