"Internal hard drive disk not recognized" için yanıtHey guys, I have a Macbook Pro late 2011. I had replaced the hard drive and the cable and I still could not figure out why it is not working. I also had restarted SMC so I thought the problem was with the logic board. But, after reading thread I realized that I needed to restart nvram as well. I still don’t know if my old hdd/cable would work or not. Anyway, thanks for such a great thread. PS: This was a helpful link btw on how to reset nvram and SMC. https://iosafe.com/helpdesk/kb/faq.php?i... ================================ Update: I still have problems. After I restart nvram, it recognizes the hard drive, but after 5 minutes, it forgets it. Any clues why?
