[Bug 1789669] Re: Cannot read some windows 10 ntfs files

This file is probably compressed using the format introduced by
Microsoft ca 2016 for Windows system files.

Doing "ls -l /c/Windows/WinSxS/amd64_microsoft-windows-l..b-onecore...."
(with the full file name) will probably return "unsupported reparse
point" when using ntfs-3g-2017.3.23. An older version would be unaware
of the format and just show a file filled with zeroes.

To read the file with ntfs-3g-2017.3.23, you need a plugin. This is not
possible with earlier versions.

For the source code of the plugin see :
https://github.com/ebiggers/ntfs-3g-system-compression
There are binary versions (not up to date) available on :

Title:
  Cannot read some windows 10 ntfs files

Status in ntfs-3g package in Ubuntu:
  New

Bug description:
  OS: Kubuntu 18.04.1 LTS.
  # apt-cache policy ntfs-3g
  ntfs-3g:
    Instalado: 1:2017.3.23-2

  I am getting an error reading a file from a NTFS filesystem (I/O error - errno=5).

  Example:
   fstab entry:
     UUID=xxxxxx /c ntfs noatime,noauto,defaults,umask=007,gid=46 0 0

  mount /c # OK
  cat '/c/Windows/WinSxS/amd64_microsoft-windows-l..b-onecore.resources_31bf3856ad364e35_10.0.17134.1_en-us_b32d47db06f00012/winlangdb.dll.mui'>/dev/null
  Erro de Entrada/Saída de dados (into english: Input/Output error).

  Using a small program I could see that returned errno=5.

  
  What I have tried:

  1. 
  This error does NOT occur with ntfs-3g 2.22 from an opensuse 15.0 installation!

  2.
  Manually installed ntfs-3g 2.22 from past ubuntu .deb files (ntfs-3d + lib).
  The error still occurs.

  3.
  Manually installed ntfs-3g 2.22 building from .tgz file (./configure,make,make install).
  The error still occurs.

  NOTE: Steps 2 and 3 were done after purging ntfs-3g and libntfs-3g88.
