Ok so i bought a new HDD to add to my system. A 4tb Seagate, i already had 4 1tbs so i wanted to remove some of them and replace it with my new one.

i succesfully installed it into my case connected its cables, checked if it showed up on my BIOS boot my computer up to give a letter to it.

But;
it shows up in the device manager.
i cant see it on my disk manager. all other devices show up but not the new one.
Also i tried cmd diskpart and list disk but i cant seem to find it there either.

You can check the ScreenShots too. im more than happy to give more information about this situation.
i blacked out confusing part because i m using a different language windows.
Pls need help thanks.
