HELP: A Windows tool deconstruted the APFS container of my SSD

[Guest 5T33Z0]

Close before Christmas I found a little tool called Windows_EFI_Mounter on github (which since then has been deleted) which could mount the EFI under windows.

 

After reboot I couldn't get back into macOS. I took the disk out of the system and connected it to another hackintosh via USB encasing to check it out. Apparently this tool "dissolved" the whol APFS container and just left EFI Partiton. The rest (approx. 120 GB) of the space is just raw data now which I can't access:

  

According to the dev this windows app does the following:

sel disk {diskCount}
sel part {partCount}
set id=ebd0a0a2-b9e5-4433-87c0-68b6b72699c7
assign letter=z

Unfortunately I have some important docs on this disk which I'd like to get.

 

I am wondering if there's a way to to restore the APFS container in Terminal so I can acces the disk again? If I use Disk Utility it wants to format the disk.

 

Thanks a lot.

No one?

I'm assuming you've tried to run First Aid on the drive? See if it's possible that TransMac on Windows can access the drive, if not then you're most likely looking at some form of professional data recovery.

I think, I will try something like this instead: https://apple.stackexchange.com/questions/393984/how-to-create-an-apfs-formated-volume-on-an-external-drive-using-terminal

Or this: https://discussions.apple.com/thread/253514208

 

I don't see how using TransMac will work since the file system for this disk is currently not defined so my guess is that transmac won't be able to access it in the current state.
