Randy, I'm going to PM you a link to a magic ISO. Download it and burn the ISO to a cd. Are you familiar with ISO images?
Once the cd is created, throw it into the problem optical drive and boot to it. It has a number of tools for getting yourself into trouble.
I have to boot it on a local pc to refresh my memory on the menu choices, but it will take a bit to get the image from my server anyway.
We'll kill the partitions and you should be able to reformat with ease at that point.
Dave
