New Gard Drive Problem

I have a total of 5 hard drives in my computer.



2 IDE and 3 SATA.



I just installed a 320 WD. I can see the drive in my BIOS but not able to see it when I open my computer in the desktop it only shows up aith 4 hard drives. i was wondering what I need to do.



I also looked in the device manager and see the hard drive and it says that it is working fine.



Thanks.

Nevermind I have fixed the problem.
