oh... I think he thought f disk as in "floppy disk", and not the old dos fdisk command... all you need to do is do what was said by sport, boot to the floppy (goto bootdisk.com or something) and assuming you dont have a bootable CD or for some reason you just HAVE to fdisk the drive. At the A:\ prompt just type fdisk and remove the primary and any logical partitions, repartition it and then reformat it.
