Chris, You might want to invest in a piece of software like Norton Partition Magic. I know that one worked for me.

On my older XP system, I can't seem to reformat my audio-only drive (250GB in size) with a larger cluster size. When I run the format utility from the context menu, it only displays available sizes up to 4KB. How can I do this? Do I need to resort to the old command line format? thanks Chris PLEASE READ THIS FOOTER AT LEAST ONCE!
