In the past I have used DT to mount an image of my animation master CD so I do not need to keep it in the hard drive. The latest update will not recognize the DT image (created originally using CloneCD - it is safedisc 2.8) The program instead looks only at the physical drives - IDE and usb. I tried various forms of creating a new image using alcohol 120% - mounting the image in Alcohol. Then I tried setting DT to safedisc emulation and grabing the image with alcohol. All with the same result: I need to have a physical disk in one of the physical drives. I have been able to run using a burned disk, but that really defeats my purpose of not having to have the physical disk in my computer.
