Hmmmm .... I *KNOW* I attached the script I used, but it didn't make it

# Install FreeBSD 9.3R on gmirror/gstripe UFS partitions (GPT or MBR), 2 HDD's.
# FreeBSD 9.3R has nice and simple partition editor (Expert mode).
# Still, if you want gmirror/gstripe setup you have to use "Shell" mode and do things manually.
# This guide will help you create a FreeBSD system using gmirror/gstripe by hand.
# Boot from FreeBSD 9.3R installation media.
# Start installation, answer the questions until you endup on "Partitioning" screen. Choose "Shell" here.
# If the drives are *NOT* empty:
gpart destroy -F ada0
gpart destroy -F ada1

# Create MBR partition table
