硬盘安装错误

我在跑步Ubuntu 18.04，有（至少有）两个硬盘：一个 650 GB，安装操作系统的位置（其中一个分区）以及另一块 2TB 硬盘它包含（保存）几个分区 - 所有分区均用于备份不同类型的数据 - 工作，照片，音乐等等。

有一天，电脑启动的时间比平时长得多……启动后，我无法挂载任何分区来自 2TB 硬盘...这是我收到的消息：

Error mounting /dev/sdb3 at /media/aleksandar/a69489c8-7af7-41b1-bfa7-f83925a78354: Command-line `mount -t "ext4" -o "uhelper=udisks2,nodev,nosuid" "/dev/sdb3" "/media/aleksandar/a69489c8-7af7-41b1-bfa7-f83925a78354"' exited with non-zero exit status 32: mount: wrong fs type, bad option, bad superblock on /dev/sdb3,
       missing codepage or helper program, or other error

       In some cases useful info is found in syslog - try
       dmesg | tail or so.

以下是 的输出dmesg | tail：

:~$ dmesg | tail

我能做些什么来恢复数据？

===编辑（谢谢@guiverc): 提供输出smartctl：

我尝试了不同的命令，例如启用智能命令部分，但结果相同：

:~$ sudo smartctl -s on /dev/sdb

答案1

这两行不现实！

User Capacity:        600,332,565,813,390,450 bytes [600 PB]
Logical block size:   774843950 bytes

我猜你的硬盘可能已损坏或计算机的某个组件出现故障，因为 2TB 硬盘无法容纳 600PB 的内存。你应该更多地寻找硬盘恢复，就像你的硬盘已损坏一样。
