Question: Ok, so I know what hiberfil.sys is, and I want to use hibernation on my laptop.

But I have another hard drive active in my laptop, it's taken from my old one... and I want to get rid of the hiberfil.sys on that drive. But even with admin privileges I can't delete it.

Any ideas?

Answer: 
For forcing remove of hibernation file and mounting it use this:

```
sudo mkdir /media/Windows
sudo ntfs-3g -o remove_hiberfile <device> /media/Windows
sudo umount <device>
sudo mount <device> <mountpoint>

```

Instead of `<device>` use the correct device like /dev/sda4

**Update**

Sorry, I don't know why, but I thought you want to mount it on linux.

So, for removing it you can use a Live-CD, like ubuntu, and execute these command above.
**Right click the drive**, click **Properties**, and go to the **Security** tab.

Use the **Edit** button to give **Full control** to Users and Authenticated Users.

After that, you should be able to delete the file via the command prompt (make sure that you're using the correct current directory):

```
del /f hiberfil.sys

```

That should get rid of the file. I recommend changing the permissions back afterwards.
