Any ideas > how to correct it? TIA. Yes: Seems that your system can't seem to initialize UDMA support and falls back to PIO instead. This may happen if you have something in your system that is not suitable for use with UDMA. I'd check the following: 1) Do you have the 80 pin cable between the motherboard and your HD? A normal 40 pin cable won't do it! 2) Is UDMA enabled on your HDD and in your mobos BIOS? Some HDDs have a software utility that can be used to disable UDMA support. SOmetimes a jumper can also be used for that purpose. Make sure your drive is UDMA enabled. 3) Do you have anything else but a HDD on ad1? If so, disconnect the additional devices and try again. That's what comes to my mind right now. Good luck trying around...
