Thanks for the reply. I have tried uninstalling the ASPI layer, tried 4.71b, 4.71, and 4.60 with no luck. I get the error every time pictured below. Very puzzling.
Have also tried the drive set as master by itself on the cable, and as slave which is its normal setup. Never had a problem like this flashing a Lite-On drive, including my 411S in my other machine.
Puzzling indeed, almost worth drinking another beer over.
