I am trying to access some individual files from a Windows 7 backup created by means of the built-in Save and Restore functionality, from within Windows 7.
The backup data is stored in .vhd files, in particular a 160 GB file. I can attach it in disk management as described here.
The disk is shown as an NTFS volume and mounted to a drive letter, but there is no preview on the occupied/empty disk size. When I try to open the drive in Windows Explorer, I am just getting the error message Access Denied.
I have tried opening the .vhd file with 7zip as described in another question, but 7zip claims there is nothing in there except for a file named disallowedcert.stl of some 10 MB.
Furthermore, it does not seem to be a permission problem, as suggested in another forum thread. The .vhd file belongs to the current user of the computer and there are no access restrictions to them or the local administrators, as far as I can tell from the file properties.
What is going on and how can I open that .vhd file?
