我也遇到过其他类似的问题，但这些解决方案都无济于事。我的外置 USB 驱动器不再工作。

尝试了几种方法之后，USB 被列出了，但仍然无法打开它，并且随机地不断抛出“操作已待处理”错误。
有什么方法可以保存数据并修复磁盘？

答案1
您的硬件有缺陷：立即更换。
日志显示磁盘不可靠
例如：[4822.411999] Buffer I/O error on dev sdb1你的系统找不到驱动器返回错误...这是硬件故障的常见迹象。[感谢@ThomasWard]
smartctl 输出显示磁盘接口缺乏进一步调查的能力。
您可能能够从磁盘中保存一些数据，但这是硬件和数据恢复问题。Ubuntu 没有神奇的咒语来修复损坏的硬件。AskUbuntu 上已经有很多关于如何从坏掉的驱动器中恢复数据的相关帖子。

我也遇到过类似的情况，可能是因为设备被不恰当地移除了，没有卸载。journalctl -xe -p 3

我检查文件系统使用 GNOME Disks ( gnome-disks) 时出现一些错误。使用修复选项修复：

答案3
好吧，就我而言，我只需要重命名我的 wd-drive 的卷组。我无法解释为什么这是原因，但扫描（如lvscan）显示一切正常。以下答案对我有帮助：挂载未知文件系统类型‘lvm2_member’
答案4
尝试不同的 USB 端口
为什么？WD Passport（可能）有 USB-C 输入 + USB-3.0 适配器。尝试在您的 PC/NTB 上使用不同的 USB-C 输入，如果问题仍然存在，请通过该适配器尝试不同类型的 USB 端口
在我的情况下，这种行为与损坏的磁盘一致 - 在 Windows 和 Ubuntu 上。在我尝试这个之前，我准备把它寄回去。使用不同端口的适配器而不是 usb-c 解决了我的问题。在这种情况下，似乎我的主板是问题所在
