Disable hibernation on a specific partition

After a long time googling I have not found an answer that works. I have a shared partition that is mounted on Z: . When I manually unmount that partition using mountvol Z: /p in cmd, it doesn't get hibeated. I have tried to set up a .bat script to execute that same command using the task scheduler. I set the trigger to system keel power id 42. This doesn't seem to work as the partition gets hibeated. I also found this link but I have no idea how to use it to achieve what I want: https://msdn.microsoft.com/en-us/library/dd143253.aspx?f=255&MSPPError=-2147217396 I just want to automatically unmount/not hibeate a certain partition when I hibeate windows.

Any help is appreciated.
