You can disable it in the device manager IF you have no hard drives on the same IDE controller (eg if you have a SATA HDD) - Disabling the drive doesn't work, but disabling the IDE controller to which it's connected will.

Also, if you're having trouble getting it working, make sure you're using the right CD key... I think the European DVD version and the US 3CD version require different keys.

On a related note... Starforce protection is also preventing a gore patch for the European version. Outside the US, dismemberment is removed from the game, and the difference is in the game exe. But Starforce prevents you from changing the exe. I've got the US exe, but until I have the US versions of...
-The Starforce exe
-The Starforce dll
-The CD key
-An image/mini-image of the US play disc
...I can't work this out.

PS. With my IDE controller disabled, the DVD image mounted in DT4 with NO emulation, and NO Starforce blockers running, the game starts fine.
