[ubuntu] Installing on Raid 0

Long story short I am installing well trying to install Ubuntu 12.10 onto a SCSI Raid 0 array, it has 2 73GB 15K Seagate drives I believe. I have read and read and read, no actual answers, So here is my problem, right from the get go, when I got to choose the install it shows me to drives with multiple partitions of which I cannot manipulate any part of, I am usually bad at explaining things and very scarce on detail so Ill include a picture, It is attached below I hope,

Thanks
