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 Laptop(Macbook Pro 17" late2011 with 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 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 all I used the Terminal to get those infos.

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