I have installed 6 DVD writers in Tower case.
I am using Alcohol Software to burn multiple CDS.
I have seen that about 4 dvd/cd writer finish recording early but some take long time finish and their speed is around 7x. Its not that those are the only writers doing that, some times other writer write slowly. But there are always 1 or 2 writer which takes about 25 min to write the 700Mb cd and some finish in 5 mins
Why is that. All writers can write upto 40px speed. Which thing determines the speed
