Greetings!
Last week SSD (Crucial M550 1 TB SATA 6 Gb/s) with a single whole-drive HFS+ partition (no APFS) of my Mac has failed and I (hopefully temporarily) lost about 800 GB of data on important multi-year project.
Right after I felt that SSD actually failed I connected the SSD to a Windows-powered PC and ran TestDisk 7.1-WIP and the first thing I saw was the following:
I took an image of the second (Macintosh SDD) partition using TestDisk to image.dd and saved it elsewhere.
Then I opened the image.dd with the TestDisk and did Quick Search and Deeper Search and got the attached results with quite a number of found partitions. However the scanning results are ambiguous, because before SDD fail I had a single large (whole-drive) HFS+ partition instead of large number of small ones...
What do you suggest to do next in order to recover the lost file system?
I would really appreciate your help...

Have you tried fsck as described in https://www.cgsecurity.org/testdisk.pdf ?
Can PhotoRec recover some data from your SSD ?

I checked SDD's SMART attributes and found out that it is in a perfect hardware shape.cgrenier wrote: ↑15 Oct 2018, 06:21 Have you tried fsck as described in https://www.cgsecurity.org/testdisk.pdf ?

However in the result of some research I realized that after update Mac OS to High Sierra it implicitly converted its HFS+ volume to APFS.
Therefore, to my understanding on the SDD prior to failure I should have had the folowing GUID partition table:
1) EFI partition (FAT32)
2) APFS container:
2a) Macintosh SSD APFS volume;
2b) Recovery volume.
So in the result it turned out that I didn't have HFS+ partition prior to failure (time to rename the topic .
Currently it seems that I need to re-check whole partition table.
Now, does TestDisk support/detects APFS search and recovery?
