Ok, well I've solved the issue with the raptors, those drives are already running in RAID 0 and blazing through things just fine. But my issues remain with the Seagate 250GB drives. They USE to be in a RAID 0 configuration on an ASROCK mobo before they were moved to this machine. So when I brought them over, that's when my issues started. Now, I've been able to format and delete the partitions on them, making them blank drives and being able to to be seen in Windows on their own. But one or the other cannot be seen together. So when they are both plugged in, only one is seen. I don't want them in RAID 0 anymore. I am just using them as storage drives on my main machine.
The Nvidia controller is the only one that has been working properly.
The SI controller hasn't even recognized anything. The drivers for that that I've used have been off of the ASUS site, as well as the drivers from the SI site. Right now I've been able to at least transfer the information that I want off of the old drives, and onto the Seagate drives. So I'm happy about that.
