No need to be a hostage to the desktop graphical interface. Open a
terminal, you can mount it manually.

sudo mkdir -p /mnt/sdc1
sudo mount /dev/sdc1 /mnt/sdc1

sudo mkdir /mnt/sdc2
sudo mount /dev/sdc2 /mnt/sdc2

When done,

sudo umount /mnt/sdc1
sudo umount /mnt/sdc2

If this works, it proves the system is indeed working, and you can try
to find out which kde setting is broken, or which package is missing.
