WinBtrfs cannot read any content of the home directory

[Tech-FZ]

Description

I want to recover some files stored on my BTRFS-formatted SSD containing an openSUSE Tumbleweed installation which became unbootable almost immediately after I had reinstalled Windows 11 onto an NVMe SSD I had bought. The files I primarily want to recover are my Minecraft saves - which are on my /home/nicolas (F:\home\nicolas on Windows if I didn't have the issue) directory - which Windows Explorer couldn't recognise. The DiskInternals Linux Reader was able to recognise said directory, but recovering the files from there would cost money I simply do not have right now.

The Linux Reader recognised the directory...

...while Windows didn't.

Expected behaviour

Assuming the drivers are installed correctly, the /home/nicolas directory should show up.

Steps to reproduce

1. Install the drivers as documented in the readme (excluding registry changes).
2. Restart the computer if prompted.
3. Open Windows Explorer and go to the BTRFS-formatted Linux drive.
4. Open the F:\home (replace F with the actual drive letter) directory.
5. If there are no contents, you successfully reproduced my issue.

Environment

• Windows 11 Version 24H2 (amd64)
• Secure Boot is disabled
• UEFI is enabled
• WinBTRFS 1.9

Update: Turning off "Allow files on this drive to have contents indexed in addition to file properties" in the drive properties as stated in issue #705 didn't do anything.

If your filesystem is corrupted so much that Linux is unable to mount it, it's unlikely that this driver will do any better.

What does btrfs check say?

[Tech-FZ]

I have attempted to run said command, but neither PowerShell nor the regular Command Prompt (both run as administrator) seem to be able to find the related executable. Is there another way to check?

[Tech-FZ]

Update: Neither using Windows on-board checking tool (via the Properties) nor the scrubbing feature of WinBtrfs (via the Properties) helped.

Update: It appears that the /home directory is a subvolume that not even other Linux distributions can read.

I recently was able to recover nearly all files from a partly corrupted btrfs filesystem using btrfs restore with the appropriate flags, but YMMV.
