2 problems: 1) I have been backing up through time machine using the airport extreme usb and it is only 20% done. My computer froze, and I have to start over now. Is there a way to simply backup directly from my computer and then move the hard drive over? All I know is that my old backup is not recognized. 2) I would like to have both my backup drive and printer connected to the airport extreme. Can I connect the ethernet plug to the printer or will that not work? Any help is greatly appreciated.
