I tryed to emulate a back-up of PREY but when I emulate it with daemon tools it says "Please remove disc from current CD/DVD drive and insert the original "PreyDVD" discin drive D:." please help!
So what software/hardware did you use creating the image? As I mentioned before we need more info...
I used a "HL-DT-ST DVDRAM GSA-H10N" dvd drive to make a MDF & MDS file through alcohol 120% of PREY DVD-ROM
You Prey DVD is SecuROM protected so you can use this guide for a physical backup or this running from DTools vdrive.
