Say you have a computer with dual boot, using Linux and Windows. Say also that you use the NTFS Windows partition from Linux, both reading and writing data there. Now do this:

  1. Start Windows, and put it into hibernation.
  2. Start Linux, write something in the NTFS partition.
  3. Resume Windows.

The changes you made to the NTFS partition whist in Linux will not be visible from Windows; this will manifest as either not being able to see whatever changes you made, or as "file corruption" or some bull like that.

Solution: Reboot Windows.

Nice experiment that I'd like to do but I'm just too lazy: Check if a hibernated Linux can spot the changes made to the NTFS partition whilst using Windows.
