Does this also happen to files on external devices (such as a usb key) ?

A file has also probably been created in "Win/System Volume Information/Chkdsk"
(Replace Win by your actual mount point, use quotes or escape the spaces)
which you can determine from its time stamp (02/05/2014 at 20:53:12:946).
Please post it.

When you start Ubuntu after having logged off Windows normally, what is the
output of :
sudo head -c 30 'Win/$LogFile' | tail -c 4 | od -t x2
(Replace Win by your actual mount point, keep the quotes or escape the '$')

What does the same command return when you switch to Ubuntu from
Windows through a "restart" instead of "shut down" ?

And a possible cause is Microsoft having changed the rules unilaterally.
