@kre: I don't have you or anyone on my ignore list either, I want to keep it that way too. Sorry if my comments upset you!
And for the record, I didn't actually TELL Hitman to use his original disc, I just asked two QUESTIONS of which I was waiting for an ANSWER, so I never told anyone to do anything
Now, back to Hitmans problem. It appears his DVD drive won't read his original disc then. Ideally, the best solution would be to contact Ubisoft and see if they can help, after all it's them that caused the problem in using Starforce!
Another idea would be to try and put both the CD/DVD on the same IDE channel like the Secondary channel (if not already) in a Master/Slave config and see if SFN will disable both drives then.
Buy a PCI Raid controller that supports ATAPI devices and plug both CD/DVD drives into it, that way Windows will see them as SCSI devices and so I believe there will be no need to unplug them or use SFN.
Updating to the latest nForce drivers (if using an nForce chipset) might help.
The only other way would be to somehow wire a switch onto both power cables to the CD/DVD drive so you can toggle the drives power on/off as desired so you don't need to unplug cables. You must not use the switch while the power to the PC is on though, always while it's powered down, the only problem here is knowing which wires to cut and connect into the switch and where to mount the switch for easy access?
Hope some of that helps
