Solution for 2nd SATA HDD not detected in Microsoft Windows XP

I have had a 160GB SATA hard drive as my primary HD and I recently bought a 80GB SATA hard drive to be used as a secondary storage space. I connected all the power, SATA cables correctly and when I boot my computer, it shows on the display that my WD 160GB is the primary and 80GB HDD is the slave. However, when I go on to my computer, I don’t see the new hard drive. When I check the device manager, it still indicates that it recognizes both of my hard drives.
