your problem could be the IDE cable, or the jumpers being improperly set, I Don't think its the drivers if your machine is not actually detecting the devices at all - that's a hardware fault then, and you need to open the machine and see press all cables firmly in, then try again. If still no, try one device at a time, and try checking jumper settings.
Also, check what PCI cards you have installed. In the BIOS there is an option to disable/enable the RAID controller. Make sure this is set to disable
