I have a three year old HP Pavillion Elite e9120 running Windows Vista that has a solitary hard drive appearently controlled by the motherboard's RAID controller. The hard drive is now full and I want to add another hard drive and make it a data drive. I went into the BIOS and noted the "default" was RAID. For my purposes I want it controlled by the standard motherboard IDE controller. If I change the BIOS to IDE control the disk is not read. How do I fix this mess! I just don't understand why HP would make the default controller RAID when there was only one drive!
