Lite-On 52247S Won't burn fast



I have this Lite On Drive and everytime I try tu burn at speeds over 12x I hear the drive spinning up very fast for a few seconds and then it spins down, apins up, spins down, until it kind of gives up and stays at the spinned down speed and burns at that speed.

Could it be the media I am using?

Also using Nero


edit: Also firmware is 6S0F


The solution seems to be here:

Don’t use 6s0f.


Nope 6S0D hasn’t fixed this problem. I will have to test different media. Using it with “Ridata”. I can actually hear a faint click before it spins down.
