You don't named drives in Unix
You mount them to a point in your file system.
If you wanted you could call a directory CDRIVE and then mount it to there or you could just let the automount take care of it and then use "ln" to create a link to somewhere which is logical in your head where it should be.
If you use ls -al you will be able to see various links in the file system.
your home directory can appear to be all on one disk when actually in reality the directory can be spread over several mounts or for that matter over several servers. Which can be a pain sometimes for an Admin because the user sees a directory and then can't access a sub directory and starts bitching about it. When you look into it that sub directory is mounted on another sever on another continent which you have no contact numbers or telnet access to. And its admin has been knobbing about with thier groups file and chmod and NIS+ has gone in a sulk.
