Hello,
I am currently experiencing a rather odd issue. It currently started out the following error "There is no disk in the drive" Please insert a disk in the drive \Device\Harddisk3\DR3", After following up with an article on here, I followed the steps to remove from favorites by accessing the library, and right clicking on the old VM's, and remove from Library option. After I rebooted the machine, those VM's that I removed from the library returned.
Any thoughts?
