Ubuntu :: Drives Not Listed After Removing Raid Works In Windows 7?

I have two 1.5TB hard drives (neither one are my OS drives) that don't show up under "Places", but are detected under "Disk Utility". I tried to reformat them, but Ubuntu tells me that they are in use (even they are not mounted). gparted also detects them and shows them as being NTFS parition. I have deleted and repartitioned to NTFS as well. This works until I restart my computer. The funny thing is that Windows 7 sees them just fine. More detail as to how this happened below after system specs.

System:

AMD Phenom II x 4 955
ASUS M4A79XT EVO motherboard
8GB DDR3 1333
1 500GB WD SATA drive (dual boot Windows 7 & Ubuntu 10.10)
2 1TB WD SATA drives (extra storage)
2 1.5TB Seagate SATA drives (extra storage, these are the problem children)

Here's how I got here:

Installed a dual boot w/ Windows 7 and Ubuntu 10.10. Everything was fine and ALL drives showed up and were mountable in Ubuntu. I decided to set up a RAID 1 w/ my two 1.5TB drives. I restarted, changed my SATA to be RAID instead of IDE and created my RAID 1. I then realized that through this motherboard's RAID setup, I couldn't have it copy files from one disk to the other to set up the mirror. So, after I rebooted and the RAID started building, I cut the power and unplugged my drives in a desparate attempt to keep my data. I then went back into the bios and set my SATA back into IDE instead of RAID. I was able to back up my data, but this is when the problem started.

Again, Windows 7 sees and uses the drives just fine. I copied the data I wanted from my 1.5TB drives to my 1TB drives and restarted into Ubuntu. But, no 1.5TB drives appeared under Places. I started Disk Utility and confirmed that Ubuntu does actually see the drives. However, it still lists them as being part of a RAID array (I did delete my RAID array properly through the BIOS after backing up my data). I'm not sure why it thinks that and I believe that's my problem. Also, Disk Utility lists a THIRD 1.5TB drive under "USB and Peripherals". Could that be my MB telling Ubuntu that a RAID is still set up even though I deleted the RAID pair?

What I have tried:Reformatted drives via Windows 7 as NTFS. This completed but didn't solve my problem.Repartitioned the drives with gparted as NTFS. This works until I restart my computer. Attempted to reformat under Ubuntu, but it gives me an error saying the drives are busy.Reinstalled Ubuntu (but didn't reformat). Didn't work. What I'm thinking:Flash my BIOS so my MB starts out fresh and hopefully doesn't tell Ubuntu I have a RAID anymore. Reinstall Ubuntu again (this time reformatting my OS drive).
Anyone have ideas as to what's going on? FYI I'm new to Ubuntu.
