我的笔记本电脑有两个硬盘。Windows 安装在 1TB 硬盘上，Ubuntu 安装在另一个硬盘上。一段时间以来，我无法打开/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，我不想重新格式化它，但每次我尝试访问数据时，它都会显示：
cannot perform read operation
superblock is bad
运行后sudo smartctl -a /dev/sda我收到此错误消息：

欢迎咨询 ubuntu，
我建议您运行实时发行版并检查两个驱动器
sudo smartctl -a /dev/sda
sudo smartctl -a /dev/sdb
如果您从未使用过，smartctl您可以将输出导入到文件中并将其添加到此处。如果您无法读取超级块，则可以使用e2fsck -p /dev/sdb1。这将修复您的超级块。为了确保您不会破坏，我会在那部分之前使用dd_rescue。
