I've got a 2012 non-retina MBP with an SSD. I was using it normally the whole evening and it seemed fine. I went to change my desktop and the Finder kept freezing. When I rebooted it, I got the file folder with the question mark in it, and it won't boot.
I tried booting with Option held and it opens up Internet Recovery, but that just leads me to a window telling me I need to use Time a Machine or the OS disks to do a recovery. But, of course, Apple stopped giving you the OS disks.
I tried repairing the disk, but it tells me it can't repair the disk and that I need to back up my hard drive before I format it.
What should I do from here? Can I back up my hard drive when the computer won't boot normally? And does this mean I have to buy a physical copy of Lion?
I'm not a Mac guy, but this has all the hallmarks of a failing SSD, unfortunately. If that's the case, see if you can find someone better at data recovery to pull something off. When SSDs fail, they go from shitty to paper-weight pretty quickly.
