Curses. I'm running Lion on an intel iMac. Have three external drives and two printers. There was a power blip last night and disaster this morning. Two of my external drives are not being read (don't show up in Disk Utility) and neither printer is working. Message says printers not connected. Don't know where to start to fix this problem. One of the disks not showing up is Time Machine. When I go to the TM app it says cannot find disk. Tried restarting but that doesn't help. All the externals have power but aren't being read. Internet connection OK and other apps seem to be working. really puzzled by the printers. Tried disconnecting but that doesn't help either. Never faced a situation like this before. Any suggestions?
