Réponse à : « Internal hard drive disk not recognized »The difference in yours and mine is that mine has never bend dropped I was simply plugging and unplugging the hard drive for various reasons such as upgrading to another one and test another one. Yours was physically dropped which can lead to other complications.
Réponse à : « Internal hard drive disk not recognized »This is what worked for me i first reset the SMC by unplugging the macbook from the power adapter and i held down Shift/CTRL/OPTION/ AND THE POWER BUTTON DOWN for 10 seconds simultaneously, then let them go at the same time. (Nothing visual will happen) Then I plugged in the power cable and reset the PRAM by pressing the power button and immediately after pressing the power button hold down the command/option/ p/r keys untill you hear the second chime and let go. Worked for me!!!!!!!!!!! I am back in the RACE Update (05/24/2017): Note: i had previously replaced the new cable and nothing worked, I performed the tape hack and nothing worked, ( I understood the logic but it still made no since for an impeccable machine that just all of a sudden stopped recognizing the brand new SSHD that would boot externally via is caddy.....you know?) The last thing I had done was connected my macbook to my big screen tv via mini display port to display port/hdmi/dvi adapter by gigaware. Maybe that messed up my settings or...
