PowerShell脚本运行后Diskpart中断驱动器号

我构build了一个使用Diskpart挂载（附加）VHD的脚本，清除了一些系统文件，然后卸载（分离）它。 它使用一个foreach循环，并假设使用相同的驱动器号来清理多个VHD。 但是，在第一个VHD失败之后。 我还注意到，当我尝试手动附加一个带有diskpart的VHD时，diskpart成功，磁盘pipe理器显示正确的驱动器盘符，但在同一个PoSH实例中，我无法连接（设置位置）该驱动器。 如果我在第一次打开PoSH的时候做了一个手动的磁盘分区，那么在这个实例中，我可以附加和分离所有我想要的，并且每次都得到驱动器盘符，但是当我运行脚本的时候，使用。 有什么我需要做的重置脚本中的diskpart？ 这是我正在使用的脚本的一个片段。

更新：新的psdrive不允许你挂载一个VHD（或至less我还没有find一种方法）。 我发现的是我上面描述的问题源于使用testingpath。 不要相信我，试试这个：打开一个powershell会话并挂载你的vhd（使用gui或者diskpart），它们运行一个'test-path I：\'（或者其他任何作为驱动器盘符出现的） “真”（这是你想要的）。 我卸下磁盘并再次运行'test-path I：\'并得到“false”。 还是很好的反馈。 我再次安装磁盘（或另一个磁盘）并运行“testingpath我：\”它回来为“假”（应为“真”），您不能导航到PowerShell实例内的驱动器号。 如果我打开一个新的会议，我可以导航到我：很好。
