My brother bought his wife a netbook for xmas. When he plugs his external (that he uses on his laptop and desktop) hard drive, the netbook doesn't recognize it at all. No sound, no pop up window, nothing under My Computer. I don't really have alot of details but I do know the netbook runs WinXP. I did tell him to open up Device Manager before he plugs in the device to see if something changes in there but haven't heard back from him yet. Anything else you guys can recommend?
