Help!!!! Question about Vista and SATA HDD

hi
I just purchased 2 Hard Drives from friend,
one is WD Raptor X 150 GB
WD1500AHFDRTL (please Google it to see the detail)

another one is Seagate 500 GB
ST3500630AS (this model can find in newegg.com)

and I already had one Seagate 500 GB (different as above seagate,same cpacity but different model) in my computer and this one is running perfect; however, when I was trying to install Vista into the raptor X (Vista home premium 64 bit) from my DVD drive. Vista could not show my 2 new hard drives. I had tried about 5 hours, I checked cable and power core, all things are connecting competely and I could see all those drives in my booting screen and CMOS. I really tired and I don't know how to do... Please help me to solve this problem... Thanks

Motherboard: ASUS Striker Extreme 680i Nvidia Northbridge Chipset

ok, I just find out.. I can see all of my drives in Device manager under the ATA Serial controller port 1 and port 0.. but I cannot see the Seagate 500 GB HDD show under My Computer... how can make it to show up? and do I have to format my current HDD to install Vista into my Raptor(I unplugged my current computer and tried to install Vista but Vista cannot find my Raptor X)? Please Help... PLEASEEEE

Disconnect other drives - if the drive is OK it will see it
