I have a Western Digital AC418000 Specs. I have an Abit KT7. My bios is set to ultra dma enabled, and pio mode is set to auto. In win2k I goto my device manager and look at the IDE ATA/ATAPI controllers and see that under primary IDE channel device 0 has DMA selected if available. But under current transfer mode it says PIO mode. This doesn't look good. Did I not install my via 4in1 drivers correctly. Is PIO mode the best my hard drive can do. Is there a program that I can run to get a better picture of what pio mode my hard drive is in. I used the datalifeguard tools to ensure that my hard drive is in ATA 66 mode. I have the proper cable. Any suggestions.
