Is there any way possible to partition a computers hard drive so that, aside from the boot drive (C), let's say, (D) has 10GB storage capacity -- is it possible to make the (D) 10GB partition show up as a logical drive on *another* computer by connecting the two via USB 2.0/Firewire? (i'm thinking along the lines of an external hd enclosure's functionality, however, since I already have a fully functional computer that is about that size, I might as well use that for dual functionality.)
