Using Kubuntu 17.04. I cant add or delete files from my internal HDD. The HDD is mounted via Dolphin and shows that I am the owner and I have permission to read/write to it.

But if I remount it using 

 sudo mount -o remount,rw '/media/salu/B66697C066978033'

then I am able to write to the HDD.

My queston is why I cant write when mounted through Dolphin? And how do I get Dolphin to mount it correctly on its own

Here is some extra information to help you guys solve my problem.

Output for fdisk -l :

Units: sectors of 1 * 512 = 512 bytes

Ok, I solved the problem. Its not a problem related to Dolphin. Apparently I couldnt write even after re-mounting. So when I used mount -o rw /dev/sda3 /media/salu/dcommand it gave me the following error message:

Metadata kept in Windows cache, refused to mount.
Failed to mount '/dev/sda5': Operation not permitted
The NTFS partition is in an unsafe state. Please resume and shutdown
Windows fully (no hibernation or fast restarting), or mount the volume
read-only with the 'ro' mount option.

Note: (/media/"username"/"folder name") path is different for everyone)

The solution to this problem is given in the link below:

Unable to mount Windows (NTFS) filesystem due to hibernation

A short summary of what I did (summarized from the link):

Open Windows 10 and disable "fast startup"

  1. Open Control Panel in the small icons view and click on Power Options.
  2. Click on Choose what the power buttons do.
  3. Click on Change settings that are currently unavailable.
  4. Uncheck "Turn on fast startup (recommended)".

Also disable hibernation in Windows 10

Open an elevated Command Prompt (right click on the shortcut, click on “Run as Administrator”), and input:

powercfg /h off

Shutdown Windows and boot back in Ubuntu. You should be able to write in your drive now.

Although the workaround with removing the data that marks the drive as "please don't change anything" through the official way of letting windows remove it may work in some cases, this might not be possible (as it was for me) because the operating system that is installed on the drive in question can cease to function and thus a solution that works directly without having to rely on a different system might be preferable (not to mention faster and your only option).

With root priviliges, you can accomplish essentially the same thing by running your file manager with sudo in front. In the case of Dolphin, this is no longer possible as of version 17.04 but you could either edit the code and compile Dolphin yourself or use a different file manager that allows being executed as root like Nemo or Nautilus.
