You may be running into a problem trying to mount an exfat USB drive for the first time in your Fedora OS:
$ mount /dev/sda2 /media/storage1/ mount: /media/storage1: unknown filesystem type 'exfat'.
You will need to install fuse-exfat as follows:
$ wget http://download1.rpmfusion.org/free/fedora/rpmfusion-free-release-$(rpm -E %fedora).noarch.rpm $ rpm -i rpmfusion-free-release-$(rpm -E %fedora).noarch.rpm $ dnf install fuse-exfat $ mount /dev/sda2 /media/storage1/ FUSE exfat 1.2.8
