[Bug 1280574] Re: Files modified on NTFS partition are seen as corrupted files in Windows

No, I copied a file to my USB flash drive and was able to access it in Windows and copy it to an NTFS partition.

File attached.

The output in both cases is:
0000000 0001 0001
0000004

Title:
  Files modified on NTFS partition are seen as corrupted files in
  Windows

Status in “ntfs-3g” package in Ubuntu:
  New

Bug description:
  I have Ubuntu 13.10 and Windows 8.1 installed, both 64-bit (dual
  boot). Whenever I create or copy files to any of the NTFS partitions
  from Ubuntu, these files get deleted once I login to Windows. When I
  login to Ubuntu again, the files are not there. I shut down Windows
  properly and do not hibernate. I have disabled fast startup option in
  Windows, and Fastboot from BIOS. So it is not a hibernation problem.
  The same problem occurred when using Linux Mint.

  I have been able to find the exact event log concerning this issue in
  Windows Event Viewer, it says: "The file system structure on volume D:
  has now been repaired." and in the details section:

    RepairDataLength 152
  ...
  Note: "line-mozart.avi" is the name of the file that got deleted this time.

  Since Windows sees the modified files as corrupted files that need
  repair, I think Ubuntu does something wrong when saving files to NTFS
  partitions, and it is probably a bug in NTFS-3g.
