USB flash drive

I recently purchased a shiney new USB flash stick and it works fine on my Fedora Core 2 box at home. It is accessable under /dev/sda, however on the college FC2 machines I can only mount memory sticks as /dev/sda1. I obviously can't change it, so how can I change my memory stick to be accessable at home as /dev/sda1? It sounds like I'm going to have to partition it, but I want have all the space accessable, so does that mean I'd have to partition it into only one partition? Does that even make sense?
