MBP late 11 running
Samsung Evo 850 250GB internally.
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):
Weird thing called Synthesized
• 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
Preboot. Tried to recover data from
macSSD partition and fortunately almost all important data was intact and almost all files were healthy and readable/playable. That's why I think it may just be a corruption of the
4 lost partitions found by a recovery app

▸ Note5: I had ~3-5 GB free space on the SSD at the time of crashing
Please help me repair the disk and take back the OS. The drive looks like healthy and repairable.
