Hm,
I guess there were similar problems and questions some time ago, which I
followed a little bit and I was told that you have to "fdisk" the disks
as "fd" to use them in a raid again.
The value "fd" has to be typed in as the partition-type of the disks.
Hope, I am right (but I think, it remember it in the right way).
Greetings, Dietmar

A guess may be one solution but not the only one ;-)
