Are you absolutely sure that it shows up as two devices?  If you
remove the USB stick do both /dev/sdc and /dev/sdd disappear?  If they
don't then remove them 'manually' using umount.

When both /dev/sdc and /dev/sdd have gone (with the USB stick
unplugged) plug it back in carefully and see if you really get both
devices back.
