Very surprisingly the transfer rate test doesn't function any longer. It aborts when being started with
No blank media inserted.
My first thought was this might be related to the change to version 4.50, but I get the same error message under 4.11 and 4.07, so I don't think CD-DVD Speed is the culprit.
System is Windows XP Pro SP2 newest patches applied, burned and scanned on LiteON LDW-811S externally connected via USB.
Does anyone has an idea how to solve this?
Many thanks in advance.
