Diablo 2 LoD

I have tried to create a 1:1 backup of this cd but all the backups I make of this game lets me install the game but when I try to start the game it says to enter the CD. I will be using this back up at work too so the backup needs to work on all Drives, not just mine. What settings should I use?

Burner- PX-16sa SATA
DVD Rom - Samsung

No settings just try alchol 120% and when your creating the image just put the settings on SECUROM *New [Illegal advice deleted. … philamber :cop: ]
PS if you try to copy it use your Samsung and burn with your PX-16sa SATA
