I've tried to wake up my Mac Book Air from sleep today, but I got a black screen.

After waiting 10 min, I decided to shut it off by holding the power button a few sec.

After restarting, I had a question mark folder flashing. So I searched and found topics like this one : Can't boot Mac, only shows a Folder with a Question Mark?

It appears that my hard drive won't show up at all.

That is to say, if I chose the most brutal solution, i.e. reinstalling Mac OS, I can't find any disk where to install it!

It's as if my hard drive had completely disappeard!!

I've tried to boot on a linux live USB drive, but I got the same problem, it doesn't find any hard drive on my Mac Book Air.

Is there anything else I can do?

I understand my hard drive could crash badly but c'mon, I can't even find it anymore!

  • It is still under warranty !

  • My math sucks, but mid 2012 and it is now mid 2013! whatever, so I assume you tried all recovery methods.

Your hard drive could be physically separated from the rest of the computer (i.e. the cable could have broken). This is thus not a software problem but a hardware problem. Your computer may need to be open then. You should take it in for repair.

  • Genius guy suggests it's a hardware problem and that the SSD is dead. I will try to make them test the connector first. Commented Jul 22, 2013 at 7:53

I left my Mac at the Apple Store, they brutally changed my SSD. I'll never know what was the problem.

However my laptop has been cleaned and I can restart installing softwares fresh as new.
