I would be curious to see how the Disks app is mounting the volume.

Unsupported reparse point

When mounting an NTFS filesystem for Windows 10, and reading files or directories, you may

  1. see broken symbolic links to ‘unsupported reparse point’, or
  2. see the error message cannot access some_file: Input/output error (in this case you see Could not load plugin /usr/lib64/ntfs-3g/ntfs-plugin-80000017.so: Success in the journal).

The reason for this are NTFS reparse points, used by Microsoft to extend the file system. NTFS-3G does not support some types of reparse points by default. NTFS-3G plugins may be used to provide compatibility with a part of the features defined by the following reparse points

  • System compression: also known as “Compact OS”, this feature provides a stronger, executable-optimized type of conversion than NTFS’s old LZ77. Use the ntfs-3g-system-compression-gitAUR plugin for read-only support, or run compact.exe /CompactOS:never in Windows to disable.
  • Deduplicated files: this is a Windows Server 2012 feature providing block-level offline deduplication. Not yet packaged in AUR.
  • OneDrive files: OneDrive files are stored as a special volume on Windows. The ntfs-3g-onedrive-binAUR plugin gives read-write access only for files marked “available locally”.

See this page for further details, and archive.org for downloads.

Setting that compact.exe /CompactOS:never option in Windows seems like it might be worth a shot. Obviously the Disks app is using some other method; I’d still be curious to hear about that if you can find out what it is doing.
