In a earlier post I wrote about how important it is to have your data backed up. On my Macs, my main backup utility is Time Machine, which comes pre-installed with the Mac OS. Time Machine can also back up external hard drives, even though it may not be obvious how to do it. This article shows you how to change the default settings to do this.
Last night my Macbook Pro would not wake up from sleep. After jiggling the mouse and hitting the space bar a few times I powered it down. I powered it back up, and I could hear it booting up, and could feel the hard disk move, but there was nothing on the screen. After a little Googling I suspected the video driver was dead.
