spark up terminal, then change drives till you are at the root of the drive you want to erase, and use "rm -r" no quotes
then go buy a book on unix and learn how it worked. I think oreiely has a good one for OS X users

Okay, before you goof and lose ALL your data, reverse the above instructions:
Buy a book, read on the web, read "man rm", etc.
Then issue the command.
You can do a lot of damage if you blindly issue commands written by others, without understanding what they do.
You've been warned...
The command you want to use to change partitions on your hard disk is fdisk. I haven't played with this with OS X so I can't give you step by step instructions. If the disk is mounted, you must unmount it before running fdisk.
Generally with fdisk you would start the program with the command and the device you want to partition. Something like:
fdisk /dev/rdisk0
You can then print the existing partitions to the screen using: p
You kill any partitions you do not want with: e n where n is the partition number. The partition numbers are displayed when you use p
Create your new partitions using: n. You will have to read the directions for creating partitions with fdisk in OS X since different revs of the fdisk command behave differently.
When finished, save the partition table (usually using: w), quit fdisk (usually using: q) and reboot. The partitions should auto mount.
Hope this helps.
