Files edited under Ubuntu corrupted when saving other files under windows on a shared NTFS partition

[Alexandre Bousse]

Hi,

I have a dual boot Windows 8/Ubuntu 12 on a SSD drive and a shared NTFS partition (for data storage) on another hard drive. I noticed that some of the files I edited under Linux (they were Matlab source code file) were corrupted. They actually looked like images that are opened with a text editor. By curiosity, I changed the '.m' extension to '.png', and I noticed they were screenshot of a video game I played (in Windows) just after working on these files in Linux. The games I played as well as the Matlab files were all on the shared NTFS partition. Only recently edited Matlab files were corrupted

Now I do not dare opening my code files, fearing I might lose them again if I boot with Windows.

A similar problem is described here:

I don't know about the release as I am in office now. All what I can say is that I am using Ubuntu 12 and it is regularly updated

I have no clue regarding the package. It is a silent bug that do not produce any error message.

Copying what I have just written about report 1043149 :

When the "fast restarting" of Windows 8 is enabled, the ntfs partitions of internal disk (this means including non-Windows system partition) may be left in an inconsistent state, and Windows 8 restarts using a saved copy of the metadata (instead of what is actually on disk), leading to potential data loss. The checks based on the hiberfil.sys cannot be relied on, as this file only exists in the Windows system partition. Also note that the "Shut down" button of Windows 8 does not show the kind of restarting (fast or standard) which is triggered.

The only known way to avoid inconsistencies and data losses is to disable the fast restart and hibernation. See :
