I've wiped a partition before and had windows fail to install because there was something at the beginning of the disk that needed wiping. After a few tries and not wanting to rebuild my tables, I cleared a partition on another disk. It then wouldn't install to the new disk untill I unplugged that other disk. I then replugged it after install and all was sweet (seemingly atleast).
