严重的超级块问题，无法执行输入输出。

Question

我的笔记本电脑里有两个硬盘。Windows安装在1TB硬盘上，Ubuntu安装在其他硬盘上。一段时间以来，我一直无法打开/访问我的Windows硬盘(我不知道发生了什么)。基本上，我想检索数据，我不想重新格式化数据，但是每当我试图访问数据时，它都会说：

cannot perform read operation
superblock is bad 

运行sudo smartctl -a /dev/sda后，我得到以下错误消息：

欢迎来问ubuntu

我建议你运行一个实时发行版，检查两个驱动器

sudo smartctl -a /dev/sda
sudo smartctl -a /dev/sdb

如果您从未使用过smartctl，则可以在文件中输入输出并将其添加到这里。如果无法读取超级块，则可以使用e2fsck -p /dev/sdb1。这是修理你的超级大厦。为了确保你不会破坏，我会在那部分之前使用dd_rescue。
