Vista should have no problem with any ide drive. You could uninstall the drive in device manager then reboot, to get vista to install it again. I am sure that Nero is your problem. Nero 6 is not compatible with vista. Nero 7 is infamous for its bugs and refusal to load or run. I have 3 machines, 1 xp, 2 vista. I only have it runing properly on vista ultimate, but only after the latest update. My XP machine wont even load it let alone anything else. My notebook will run but wont work fully. The latest Roxio Easy creator 9 works fine. Nero realy droped the ball on 7, I bet that is your problem.
