How to make windows drive writable under ubuntu?

I have recently dual-booted my PC and it’s giving me a bit of trouble with my drives.
I would like to be able to write to my “D” drive under Linux and Windows without formatting it.

I have tried sudo ntfsfix /dev/sdb1 but that did not help and the drive is still read-only. It works fine under windows however.

Is there something I need to change in Windows or Ubuntu to make it write-able?
