I just bought a new Foxconn nForce 6150 motherboard. I have 1-74Gb raptor, which I'd like to use as my C: drive. And 3-250GB WD raid drives. Which I'd like to run in raid 5. My question is whether or not it's possible to run these this way, or will the motherboard have a problem because of the raptor not being part of the array? So far, I've had problems trying to get it running. When I turn on Raid in the BIOS, the hard drives do not show up in the WinXP setup. Even after configuring the array in the Nvidia Raid setup. Anyone out there have 4 drives connected to their onboard SATA connectors, but only using 3 as part of their array?
