I installed the latest version, entered the correct stripe size at the right place.
Performed the scan and R studio, found a partition of 1TB, but it was marked in red. In this partition not all folders were found.
So i gave up on r studio and bought the software from reclaime. This actually gave me previews and I have succesfully recoverd my files !!!
Thanks anyway to Alt-Rtt and Networks for all your help and patience ! I got a better insight now in RAID and recovering from it !
