I'm trying to do it with a USB drive. Well, I plug in the drive and nothing happens. Usually when I plug something in my Mac will recognize it and it will open up. So what do I do? The USB drive is by HP... and I used another drive by Ultra Speed and that one worked just fine (but I can't use it anymore because I broke it... I took it out too early and now it won't let me put any files on it?). Is there a button I can press that will tell my Mac to go look if there's something plugged into the USB? hahah I don't think I make any sense. Help!
