Hey, I was looking through device manager and when looking at the IDE controllers both the primary and secondary channel show as using "Ultra DMA 2" as the current transfer mode... But, from looking at the SIS (my chipset) IDE_Utility, I find that my DVD+RW drive works at udma-4 and the harddrives work in udma-6... Why isn't windows using the higher-speed modes? I plan on backing up my harddrives and don't want to waste time backing-up in a slower speed.. Some feedback would be appreciated..
erm...cancel that I found that my harddrives were connected with a 40-wire cable instead of an 80-wire one...My DVD+RW drive was connected to the 80-wire one, so I switched the wires and now windows sees my harddrives as capable of fast udma speeds.. Now a dikspeed utility shows my HD as tranferring around 80MB/s compared to around 30MB/s before.. Still, I don't know why the speed is not closer to the full 133MB/s?
