我有一个固态硬盘我的工作站中有非常重要的数据。
它有一个 ext4 和一个 ntfs 分区。
今天早上，ext4 分区（sda1）没有挂载，并且文件系统被列为“未知”在磁盘应用程序中。运行file -s /dev/sda1返回“没有读取权限“；总体评估标记为“磁盘正常，一个坏扇区”，但尝试执行任何智能自检返回错误“sk_disk_open：输入/输出错误（udisks-error-quark，0）”。
现在 ntfs 分区也被列为未知。
请帮帮我。我不知道该怎么办！
附加信息：
该磁盘是一个三星 870 Evo。
它有重要的文件和一个最近出现故障的 Windows 虚拟机。
最近还停电了。不知道这是否有关。
