Growing a hard disk image on vBox 2.1.2

[sdavmor]

I have a 60gb hard disk image win2KOEM.vdi. I'm on Ubuntu Intrepid
8.10 64bit w/4gb RAM. I'm running vBox 2.1.2 with 1024MB RAM assigned
and 128MB assigned for video.  I need more storage space than I
originally anticipated within the virtual. I already have several
attached networked linux folders, but I want to grow my virtual from
60gb to 80gb for data that should remain in the WIndows vdi. What is
the proper way to do this so I don't lose any of this data?
