I have been looking all over the place for a bootable fdisk drive that was available in USB format.  I like the idea of using USB because I can plug it in externally and I have been having some issues with my disk drive.  The last thing you want when your computer is acting up is to not be able to use the help tool that you have to fix it.  I know that sounds confusing, but it makes sense if you have walked in my shoes.  That is why this usb drive makes so much more sense to me.
