所以，我不确定这里到底发生了什么或如何修复它......我查找了错误sudo parted并发现了这个：
https://gparted.org/h2-fix-msdos-pt.php
看起来是同样的问题（似乎用 gparted 而不是 KDE 的分区编辑器找到这个问题是无关紧要的），但在我对分区表进行更改之前，我想尽可能小心，因为我真的可以'不会丢失硬盘上的数据。
有任何建议或知道任何具体的修复方法，任何人都可以指出我吗？
我真的很感谢所有的帮助，如果您希望我运行任何其他命令发布在这里，请告诉我。
谢谢大家。
仅供参考：我安装testdisk并正在运行它，如果您需要它的输出，请告诉我。
更新“oldfred”以通过推荐的 cli 命令的建议查看：
