Hi, I have three mac notebooks (black macbook 2006, macbook pro 15" 2007, macbook pro 13" 2011). Interestingly, my 15" mackbook pro cannot wake up a AEBS-connected WD harddrive. My other two notebooks are doing just fine. I go to Finder and click 'shared' and a couple of seconds later, I can access to all the files in the harddrive. However, I have no success so far with my 15" one. Can anyone give me what might be wrong with my 15" one? The 15" one's wireless connection is flawless by the way. What is interesting is that even though my harddrive is spinning (after getting awaken by my other macbook), the 15" one is still trying to connect and fails to access to the files. Any comments are appreciated. Thanks! oh...by the way, my 06 and 07 macs are running SL.
