Windows 7: Drive missing

Hi,heres the problem,tried a bit of overclocking and it went fubar,had to reset cmos on my striker extreme to get it to boot it boot ups and my win 7 64bit and its fails.I was running 2 74 gb raptors in raid,with a 500 gb data drive.

So i booted from win 7 disc to do a repair,this shows my windows 7 installation in an unknown location..so tried loading raid drivers etc nothing worked.So thought i would bite the bullet and format,but im getting only 1 raptor showing up.The 2 raptors show up in bios but not in Windows 7 installation.Any ideas,ive also checked all cables,set bios to raid/sata/none still no luck in finding the drive.

Windows 7 64 bit
Striker extreme
4gb mem
quad core q660 at 2.6

(yes i know its my own fault for not backing up)
