我意外删除了主分区上的一个分区。我以为是可移动驱动器。我显然应该多加注意...我没有“保存”或“退出”parted，但看起来分区不见了！有什么方法可以撤消吗？parted 退出时会要求我保存吗？我可以直接拒绝吗？

根据以下建议，我运行了 testdisk。但是，由于它是一个加密分区，testdisk 无法正确找到分区的末尾。我现在看到这个：

You have to reboot for the change to take effect.
You have new mail in /var/spool/mail/root

答案1
来自手动的：
只有在 Parted 退出后，Linux 内核才会知道 Parted 对磁盘所做的更改。但是，键入命令所引起的更改可能会在键入命令后立即对磁盘进行更改。但是，操作系统的缓存和磁盘的硬件缓存可能会延迟此过程。
您可以退出，然后尝试恢复分区；根据您上面的信息，这应该非常简单。
如果 parted 无法恢复分区，我建议使用testdisk：http://www.cgsecurity.org/wiki/TestDisk
