[/b]I have a 40gb ide drive strickly running xp pro. i have a 160gb sata for a media/game drive. Everytime i go to copy files(music) from my external to my internal sata, my computer powers down. It's weird. I thought it was the drive but it's not. I think it's a setting. I have two sata 160's one maxtor and one seagate. They both are doing the same thing. Powering down. I havea K8NF mobo and a 4000 amd. Any suggestions? Thanks.
