  1. The xps400 motherboard has only 1 SATA controller which you have configured as RAID.

    You will need to use IDE or add a PCIe or PCI SATA controller to plug the drive into.

  2. I don't know the specifics of the way Dell manages RAID. But on systems I have used with one SATA controller that provides 4 SATA ports, even though all HDD's are plugged into ports of that one controller, they are NOT all part of a RAID array. There is RAID management software built into the BIOS and you use it to configure any RAID arrays. That starts by specifically designating which connected HDD's are to belong to which RAID array you create. By default, unless you assign an HDD to a particular RAID array, it is NOT a RAID drive. It is just a "normal" stand-alone HDD you can use.
  3. Hello,

    The Dell computer layout has room for only 2 HDD's inside.
    It does list 4 SATA ports on the board however.
    The CD/DVD is connected by an IDE cable.

    One other consideration with the limited space is to purchase an USB to SATA external enclosure, place the HDD in that, and connect it by USB port on the back. Here is just an example of an external enclosure if that might help. Cost ~$28.

    With your computer, you would need a USB 2.0 version, and I'm assumming the Seagate HDD is a 3 1/2" size.
