This (almost same) problem happened to me as well. It was solved with a
wipe of all information from the disk by using DOS fdisk to eliminate the
partitions and overwrite the MBR with fdisk /mbr . That worked and I was able
to create the new raid configurations.
Could it be that the "persistent superblocks" are a bit too persistent?
