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:
- Start Windows, and put it into hibernation.
- Start Linux, write something in the NTFS partition.
- 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.
