Actually you were "overspeeding" the burn to 18x, and the blanks are rated for 16x.
You should still get a good burn at 16x, but on most newer burners, the best burn quality is achieved at 8x and 12x speeds
By the way, where are your Verbatim blanks made? India? Singapore? Somewhere else? It's written in the packaging/box/spindle.
Not sure where theyre made nothing on spindle and packaging in the bin. Came from Staples in the UK if thats of any help!
I understand the Indian produced ones are the best and will check next time. Normally use the phillips and never ever experienced the same problems.
What you say figures, I didnt realise the burner would try and exceed the disk speed limit of x16, I would've thought the drive would slow to the speed of the disk (we live and learn).
Thanks again will keep you posted/
Ever the optimist ^^
