I have been running a system with a Maxtor 120GB Ultra ATA hard drive for about 2 years now. Its getting to be full so I bought another hard drive(Seagate 320GB Ultra ATA). I plugged it in and set my Maxtor as the master and the Seagate as the slave. However, when I try to start windows. It goes past the screen that says Asus motherboard and so on then before it gets to the Windows XP loading screen the screen just goes black and hangs there. I can go into bios and it shows that it recognizes both hard drives. Everything works fine if I have one hard drive in, but when i try to run both it doesnt work.
