I reinstalled 10.8.5 back. I gave up on that since it gave me problems.. This is NOT a dev problem or 10.9 problem. This is a hardware issue, in my opinion.

Ok, i did the following from that post:
1. Disconnected almost all connectors from logical board (no mega power and no battery power)
2. Pressed power button 3 seconds to grain the mainboard of static electricity
3. Installed the old RAM (the one that came with my (macbook pro)
4. Disconnected cable from HDD and logical board and checked it for contorsions, for dust etc.
5. Booted from my external HDD and saw that my other internal HDD was present now within Disk Utility and Finder (desktop)
6. Shutdown the computer, reseated the 2x4 GB RAM modules i usually use, carefully installed my 1 TB hard drive back and computer started normally.
- This may have been a workaround. For a notebook to have this issue is a big problem. I will never know when i will shut it down or use it and the HDD will disconnect while in use.
Thank you for you help.

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?

I would use tools, but i have another hard drive. When i install the second one, it still doesnt get any power. Somehow, if i disconnect the cable from logical board and hard drive, take the battery out and put it back, that makes my harddrive back on.
Now, after i managed to start it, it hangs my applications, some are not starting, others are continuing to run until the whole OS fails and i have to hot reboot the laptop.
