I just installed a 240 gig SSD in my computer and used my USB recovery thumb drive to load software and selected to set it the way it was when new. I understand the 1.46gig recovery partition but I don't understand why it also creates a 13.55 gig primary partition with no drive letter. Seems like wasted space and it did the same thing on the original 640 gig drive. Go to the Start search window and type diskmgmt.msc to check your C drive.
How do you think an HDD or new HDD gets recovered to out-of-box with all the software it came with? The 1.46GB partition is just the recovery operation software. The 13.55GB partition is all of the original software installation.

I guess that means I can eliminate that partition should I need more space since I started with a blank drive and a 16gig USB thumb drive. It apparently doesn't serve a function unless you recover from the drive itself.
