I got my computer back today and a Rosewill SATA + Ultra ATA Raid Controller was installed to bypass the messed up capacitors on my motherboard. I am using the 1 TB hard drive as the sole drive. My understanding is that at this point I am not using raid, but if I want to add a second hard drive I will have to and I will likely have to reinstall Windows. Is that true? I presume I can still use external hard drives and the like since they use USB and not the motherboard or controller card. Is that correct?
