OK everything was going fine. I had replaced my NEC DVD+RW 1100A with a pioneer 109. Read and write rate was fantastic. Then I reinstalled my NEC to run next to it. I had problems with the read and write speeds with it. Max was 1.4. I figured out that it was set on master still so I took it out and switched it over to slave. Still slow. My pioneer was still reading at around 10x, burn at 4x regardless. So I checked the PIO DMA mode the secondary IDE channel was pio only on device 1 device 0 was dma if available, all this I tell ya on secondary channel. So I uninstalled it and rebooted now device 0 and 1 are both "pio only" and my pioneer reads at a whooping 1.9 and the NEC still at 1.4. I have tried many times to unistall it switching to dma in available in the "Transfer mode box" Any ideas?
