My hard drive is missing 14gigs. What happened? [slave drive] [harddrive]

Q: I have a 120GB hard drive as slave drive so they do not have the OS on it. It shows as 111gb in My Computer. No big deal. Bit annoying, but I know the whole deal 1000/1024. But now, he says Ive used and I only have 107gb 4gb free. That adds up to 111gb, so everything seems fine until I hilite all my folders, right click on properties and it tells me that all files on the hard disk only 93.1gb used. Where are the other 14gigs go?
