Moving/Removing Filesystems

[Tom Moyer]

I have a Windows XP installation on the first 20 GB of my harddrive
and I would like to remove it and expand my FreeBSD install to fill
the entire disk.  Is there an easy way to do that without formatting
the entire hard drive.  I've updated the system to 5-STABLE and have
installed many ports and I don't want to lose that (limited
bandwidth).

Thanks,
Tom
