Failed to add device 'Virtual Hard Disk', General access denied error (0x80070005)

I recently upgraded my laptop to Windows 8 to take advantage of Hyper-V in the management of my virtual machines.

To get better performance using SharePoint, I bought an SSD and I moved my vhds to the new disk. At this point, I have to change the path of the VHD virtual machine settings and when Itry to do this, I got this error: "Can not add device virtual hard disk."

I tried to change the virtual hard disk file permission, but the error was alsways there.

To resolve this error, one must perform the following steps

  • Mount the VHD (double click on the file)
  • into disk management tool, put offline the disk
  • into virtual machine settings, remove the link to the old path of vhd, add a new physical hard disk and select the offline disk

Et voila, The system can manipulate the vhds on the SSD disk :D

    I do consider all of the ideas you've introduced on your
    post. They are very convincing and can certainly work. Nonetheless, the posts are too short for novices.
    May you please prolong them a little from subsequent time?
    Thank you for the post.
