That shouldn't have anything to do with the Safety Clone, Dom -- it's just showing you both the mount point (/) and "Macintosh HD", which is the drive that's mounted.

Why both are showing up, I'm not sure -- try rebooting.

Removing the Safety Clone would just be a matter of erasing it: but, keep it around. What I'd suggest is, next time an OS update comes up, update the Safety Clone, boot from it and install there *first*. Make sure it's OK, and if so, boot back and then you can install it on the main drive, assured that things are going to work on your system!
