Why doesn't Fedora 27 file manager show NTFS drives?

edit

Whenever I plugin my external hard drive, it doesn't open automatically. Also, the my internal drives doesn't show up in the file manager. Earlier it used to. However I can mount them as follows:

sudo fdisk -l

I can view my windows D drive files using this:

sudo mkdir /mnt/sda4
sudo mount /dev/sda4 /mnt/sda4
ls /mnt/sda4
