I currently have a DVD Pioneer 106S which the specs say has UDMA/66 support and a Plextor 12/10/32 CDRW on my 2nd IDE cable. The question I have which cable should I be using for these 2 drives and will it affect the performance of the drives. I currently use the older ata33 cable but when i enable dma on the pioneer I usually get crashes in 2000 and XP when using the drive. Will using the ata66 cable on the plextor affect the performance of that drive? I tried checking the specs on the Plextor but do not know if it supports UDMA66, it says it is PIO Mode 4/DMA Mode 2.
