This is my first time on communities.  But I do not understand why the system can accept a HD when can boot it when connected via USB.  ??

MacBook Pro, Mac OS X (10.7.4)

    Apple Genious, aparently this is a hard question.  Can somebody tell me if there is a problem with the power supply of Model A1278.  The 1TB HD is a Western Digital Scorpio Blue (WD10TPV) of 5VDC:0.60A.   Class B


    I'm rationalize the problem, but I don't have the information.  My laptop continues asking for more HD space and I'm worry if I may loose information.  HELP.

    The HD can be used for booting when it is connected via USB. But when you open  machine an install it, a blank screen appears.   When you start it and press option key a folder with a question appears on screen.  I search the discussions and there are multiple unbooting HD but not these esemario that it boots in USB but not inside the Mac


    Thats why i return to you.   I need more storage at my Mac. Rush & desesperated
