boot osX - getting rid of it


I have had a boot osX partition on my computer since I started using osX. I've noticed that other people have had the same problem but haven't found a fix. Does anyone have any suggestions?

It shows up like a regular drive in os9 and osX and can be dragged into the trash but reappears on start up. It is usually invisible. Should I try resedit? Will putting a (.) in front fix it?
