Hi guys,

i've encountered a terrible problem: my internal Hard rive doesn't receive any power when i start my Macbook Pro mid 2012, 13 ".

Everything started yesterday when i wanted to upgrade to 10.9 Dev Preview 1. Everything ok, upgraded to Dev Prev 2 and suddenly Finder stopped working, disaappeared and i turned the computer down. When to start it i found a folder with a question mark.

Tried to boot from Recovery, the partition was missing.

I found out at home, later that day (today), that my internal hard drive does not power on when i start the laptop. Screen is ok, Optical drive ok, hdd not. No power whatsoever. Randomly, it would boot, i managed to put another OS, rebooted several times, noticed again that it doesnt juice at all.


Now i'm on a copy of that os on my external USB drive, booted from Option Key.

What seems to be the problem?, Cable? Logical board? The second hard drive doesnt get power either. I tried to swap- no dice.

I resetted SMC, PRAM etc, nothing works.


I don't want to get to Apple support, i really need my laptop.


Any help would be appreciated.



MacBook Pro, OS X Mountain Lion (10.8.2)

    Since you are working on 10.9 you will have to post your query on the developer forum.

    See if these procedures help:



    Do not discount that the connection cable to the internal HDD may be faulty.

    Since you are reporting sporatic or random issues of your HDD not receiving power, it could be an indication that your interanl HDD is failing.  Some HDD's tend to fail failroy soon after they are put into work, and others later, but eventually all HDDs do fail.  I believe that Google has shown somewhere that after 2 years of use, the liklihood of an HDD failure goes up dramatically with each passing year, and since they have a large number of HDDs they user in their "stoarage farms" they would hsve a good statistical base to work with.


    I would suggest that you use a few different tools to verify the health of your HDD, in case it is starting to fail.  You don't want it to totally fail and to lose everything on it now do you?
