Hi Gerald, Following the instructions on the BeagleBoard.org - getting-started <http://beagleboard.org/getting-started> webpage, my team lead and I have been powering up the BBB by using the provided USB cable to plug our Beagle into our computers. We didn't find instructions on powering it down. So, we have been powering it down by simply pulling the cable out. By doing this, can we also get corruption? If so, where is the shutdown procedure documented?
