you want to go to the internal drive in the time capsule?
don't think so.
you might have some success going to an external USB drive, then moving that drive over to the time capsule.
otherwise, if you have the new air with thunder bolt, sounds like an excuse to buy the new cinema display also as it has a gig-ethernet connection on it.
you'll probably just have to set it up and let it run, will take a bit but shouldn't be to bad.
make sure you're on the N network for the fastest speed.
