Thanks energy 1959 for the test.
It is a "creating a data disc" not a scan
What is limitating the speed to 8x P-CAV in this single layer burn ?
Is it the MID code that you have used ?
By the way the question is:
is the only way to scan this disc (with this drive) using CD-DVD Speed to flash the drive back to a BenQ 1640 ??
