Second SATA drive not seen

I have an MSI K9A2 platinum with a Phenom II 940, 4GB PC8500 running winxp SP2. 2 Seagate Barricuda SATA drives installed 1TB and 500Gig
the 1TB is in SATA slot one and runs fine. The 500Gig in slot 2 is formatted with win xp installed but is not seen by my bios or windows. Want to run in a non raid array. Did the whole disk management search and no luck. Anybody got any ideas?
