I have an HD image of Toca 3 never used because of StarForce protection problems.
I have tried all the suggestions posted (install virtual drive software, disable IDE drives, and so on..) but nothing was good for me.
Yesterday reading some posts in this Forum I downloaded the Toca 3 .mds file from
www.copybase.ch (USA version) :
1) renamed it with the same name of my image file, leaving .mds extension for the file and .mdf extension for the image file.
2) mount .mds with Alcohol 120% (latest version)
3) install game
4) reboot
5) Run the Game and ... it WORKS!!!
No need virtual drive software or disable IDE drives in Drive Manager or something else...
