我有一台 Acer Aspire S3，安装有 Ubuntu 12.04，/分区在 20 GB SSD 和/home320 GB 硬盘上。两者都是 EXT4。
我正在正常使用 Ubuntu，然后它就卡住了。我无法使用 ++ 在终端之间切换Ctrl，Alt然后Fx我进行了 REISUB。
好吧，系统不再启动。它显示以下消息：
error: hd1 write error
然后仅使用 BusyBox 启动。
我已经使用实时 USB 启动并尝试安装这两个分区。/home在 320 GB 硬盘上安装没有任何问题。但当我尝试/在 20 GB SSD 上安装时，它显示错误：
Error mounting: mount: wrong fs type, bad option, bad superblock on /dev/sdb1,
missing codepage or helper program, or other error
In some cases useful info is found in syslog - try
dmesg | tail or so
的结果dmesg | tail：
ubuntu@ubuntu:~$ sudo dmesg | tail

然后我尝试fsck执行日志，但没有成功：
ubuntu@ubuntu:~$ sudo fsck.ext4 -v /dev/sdb1

如果我执行这两个过程中的任何一个，它总是重复相同的操作。似乎没有写入 SSD。
我也尝试删除该分区，但是没有成功。
我的硬盘坏了吗？
