I created a virtual drive and mounted the image of the 'Godfather' game DVD. The installation was done from this drive. Later when I try to run the game with the image still mounted, the game gave a message asking me to insert the game cd into the drive.
The same problem happens with couple some other game images I tried. What is wrong?. I thought virtual drive can fool the applications to think that we are running from a physical drive. What is the use of virtual drive if this is the case?
