Why is the option to Initialize Disk greyed out after I have attached a VHD?

Question

I have attached a VHD inside windows 7 and gone into disk managementt. When I right click on the drive which currently states it being as deallocated, the option to initialize the disk is greyed out. Does any one know why this would be and how I can solve it?

Answer 1

Have you tried to close and re-open disk management? The only other reason could be that you don't have enough permission to the VHD file, or alternatively that there is an error with the VHD.

Try creating a new blank one and see if this error persists.
