Can not see drive in bootable media

I just bought a new corsair Force GT 120gb drive, i already had one running my OS, what i wanted to do was rework the drives and make a raid 0 array out of them, i reformated the original drive, added the new one, and disk director does not see the drive when i boot into disk director. i have updated the Bios on the drives, i reinstalled the OS and looked, windows 7 can see the drive in windows, i can see it in my bios, but when i go to disk director i do not see it, can someone please help me? email me at
