You might have plugged it into a raid port, and its not showing cause your raid isnt setup.

How do i Know if i plugged it into a raid port and how to set up the raid por†?

If you plgged it into a different color sata port then the other drive then it is. Ususally sata ports are red, not always,

You mean the sata cable? If it is , then you're right my 160 is connected via yellow sata cable while the other on is red..DO you think thats the problem?
Thanks!!

cable color aint important but actual port on motherboard is.
