I have just purchased this mother board (ASUS A8N-SLI Premium) and placed 2 GB of ddr 400. It is running window XP pro and has 5 drives all together HD, 1 DVD-Rom, 1 CD-rom) and every time I plug my 80GB USB hard drive into the computer (both device and computer end have USB 2.0) it finds the drive but crashes every time I transfer stuff to the drive or from. I have used this drive on more than one computer and works fine, but when I put it in this computer it just messes up. I have reinstalled the OS twice and still the same problem. Has anyone see this before?
