`MBP late 2011 13` running `10.13.2` on a `Samsung Evo 850 250GB` Everything was fine for months but few days ago something horrible occurred. I'm so shocked and urgently need your help. Finder wasn't responding and I had to restart it by force. But it didn't boot again and just showed a black screen. Tried several times without success which finally I had to install another High Sierra on my 2nd drive (a healthy HDD) • Here's few shots which convince me that the `APFS container` is damaged (SSD=disk0): Disk0s2 - part1 Disk0s2 - part2 Container Weird thing called Synthesized Diskutil list Diskutil apfs list Diskutil repairDisk/repairVloume • Here's few notes which probably help you know where the error lies: Note1 : Used a third party app and it found 4 partitions including VM , Recovery , Macintosh SSD , Preboot. Tried to recovery data from Macintosh SSD partition and fortunately it was intact and almost all files were healthy and existed. That's why I think it's just a corruption of the `APFS container`. ------------------------- Please help me repair the disk and take back the OS. The drive looks like healthy and Repairable.
