Disk2vhd | P2V Migration -> How to get rid of the unallocated disk space RRS feed

  • Hi,

    You can shrink the VHDX disk by following the steps below:

    1. Shut down the virtual machine.

    2. Open up a Windows Power Shell (Administrator) and first check the VHDX disk status by typing the following command:

    Get-VHD -Path "Path to your VHDX disk"

    You should see a similar result like in the screenshot below:

    3. Now if the MinimumSize is smaller than the Size, you should be able to shrink the VHDX disk.

    4. To shrink the VHDX disk, type the following command:

    Resize-VHD -Path "G:\Hyper-V\WIN10PRO\Virtual Hard Disks\Win10_C.vhdx" -ToMinimumSize

    5. Now type the same command as you did in Step 2, to verify if the VHDX disk got shrinked.

    Get-VHD -Path "Path to your VHDX disk"

    Best regards,

  • Sorry, I didn't pay enough attention to your first screenshot, you need the unallocated disk space at the end of the disk inside the virtual machine or you cannot shrink the VHDX at all.

  • Unless you have the possibility to copy everything from the "DATA (D:)" partition to somewhere else, then delete the DATA (D:) partition and then re-create it, the last option is to use third party tools.

    There is for example GParted tool which is an open source tool, below you can find a guide on how to fix virtual disk resizing issues with GParted:
