KV-80 two SATA drives

I have a XP Pro SP2 running on KV-80 (AMD 64 3000+). I connected
another SATA-2 drive and after restart, the computer hangs few sec
while windows is loading. I tested a different drive, the same
problem. Both drives are working fine on a different computer. What
can cause that, and how it can be fixed?

Thanks
