For this kind of operations I strongly recommend Darik's Boot And Nuke because it's bootable, supports all major operating systems, has support for raid, sata and ide drives and it does its job accordingly.
The package comes in ISO format for easy burning. I suggest you use ImgBURN for burning. Insert a blank CD and use the Burn Image to Disc
option in ImgBURN which is found on the main screen. After the process completes, boot the CD and perform wiping operations.
