You say it "shows a capacity far less than it should"? but I see 14G here. If you're talking about the math (14G/13G!=100%) then you might want to consider that UN*X filesystems assume a percentage of free space always avialable so it can work sanely when it does writes (I think this defaults to 9% - see the man page for newfs & tunefs) > 100% full but showing a differance of 1+ Gigs.

Make it a "dangerously dedicated" disk and it will use the whole thing. I'm still not sure what you're talking about with the 26M thing, though.
