Only 1 HDD registering

[Duque]

So I recently build my first computer with 2 wd 1 tb drives. I have alot of stuff (about 1.5 tb) and I don't want them in raid. I know I installer both properly cause when installing windows, I had my choice of which to put the os. For some reason now that I'm in windows, i only have access to one of them. What is going on? Could I have accidently put them in raid. I read my mobo manual (asus p6t deluxe v2) and all the satas seemed to be the same. HDDs in sata 5 and 6 with dvd drive in 3. Did I do something wrong? Any help is appreciated.

EDIT: Did I need to change settings in the bios in order to recognize the second hdd?

see if it appears in device manager, if it does.. you probably need to run the storage - disk management
and partition/format your other drive. if you need more help try googling disk management snap-in..
