I have found that Toast and the Disc Burner extensions don't play well together. Try taking out the Disc Burner extension out of the extension folder. Maybe take out the rest of the extensions that deal with Apple's built in burning. Then restart. Toast should se the drive now. Chris I just picked up an Iomega USB CD-RW for my G4-400 (AGP) and I can't seem to get Toast 4.1 to recognize the burner. I'm running 9.2.2 and have the toast usb extensions turned on in extensions manager. Does anyone have any thoughts/ideas as to where I might go from here?
