无法挂载没有卷的 Win10 虚拟磁盘 (VHD) - DISKPART 失败

Question

我正在尝试安装 Windows 映像备份 .vhdx 文件并为其指定驱动器号，以便我可以从备份中检索一两个文件。它过去运行良好，但现在我无法让它与来自两个不同系统的两个备份中的任何一个一起工作。

过去，我只是使用 Win10 的磁盘管理控制台来连接 VHD 并分配驱动器号。如果磁盘管理在任何地方失败，我必须使用 DISKPART 在命令行上执行此操作。有很多指南，包括这个： https://www.ubackup.com/articles/mount-windows-image-backup-vhd-4125.html

但是现在，即使 DISKPART 也无法为该 VHD 分配驱动器号，因为据报道它没有定义卷，而选择卷似乎是一项要求。

DISKPART> select vdisk file="\\rackstation\WindowsImageBackup\Jim-XPS\Backup 2021-05-18 205737\75a7e1c1-db22-4315-9afe-3852852949c8.vhdx"

DiskPart successfully selected the virtual disk file.

请注意，“列出卷”返回的是磁盘 0 上的卷列表，而不是所选的磁盘 1（= VDisk 2），而“选择卷 [#]”会选择所选卷，然后将所选磁盘更改为磁盘 0！见下文：

那么，到底是怎么回事？我们现在如何安装 Windows Image Backup 创建的 VHD 文件？这是 DISKPART 的一个已知错误吗？我知道，如果您对“选定”的磁盘进行破坏性操作，这种对选定磁盘的静默切换可能会造成严重后果。
