I have checked almost all the "messed up the fusion drive" posts and don't find any close one to my situation, so I decide to ask a question and hope someone can help me, especially @klanomath :)

Here is what happened: I connected my mom's iPad with MacBook Pro 17" Late 2011 running OS X El Capitan 10.11.5 and doing backup then I go to sleep. Next day my mom just pulled her iPad out, later I get up and find the MacBook Pro just with white screen and can't do anything. I turned it off and restart it, the loading bar runs really slow and without finishing loading the laptop shut down automatically. Then I boot it with OS X Install USB and tried to use Disk Utility to fix the problem and it can't even read the disk. After which, I used the Terminal to get this information.

-bash-3.2# diskutil list

I don't have a Time Machine backup so if all the data could be recovered I would really appreciate it!

The only solution I was able to discover is to erase and format the drive. You can do that by following these steps:

  1. Boot into Internet Recovery Mode.
  2. Erase the drive using Disk Utility.
  3. Reinstall OS X.

For more information read How to reinstall OS X on your Mac, then click on Erase a drive and reinstall OS X.

  • @Longtea As far as I can tell, no...but I'll up vote this question and hopefully it gets some more attention, just in case there is another solution. – Munesawagi Jun 14 '16 at 10:53
  • Appreciate that. – Longtea Jun 15 '16 at 17:46
