I just purchased a LG GSA-4081B (8x DVD multi drive) and using a 2.0 usb external case. I have a Dell Dimensions4550 P4 at 2.40 GHz, using WXP Home. I downloaded the free trial of CloneDVD and DVD Region Free to see how they work. I tried to copy a DVD and I keep getting the same error message: write DVD9 error possibly bad medium comes up. I'm using Ritek G04 4X 4.7GB DVD-R. I deleted CloneDVD, rebooted, reinstalled CloneDVD and rebooted (per suggestions in another thread) but I still got the same result. I downloaded the firmware from LG and still no change. I bought Memorex DVD-R's (one of the three brands suggested by LG) and still can't burn. After reading threads about ASPI layer threads, I used FORCEASPI to go back to Adaptec v4.6 and install the 4 layers. Then I deleted and reinstalled Clone DVD. I still get the same result. I'm ready to send the burner back! Can anyone give me anymore suggestions?
