Update: compiled mdadm.static on a 32bit machine and could re-add the two partitions to the array! cool! thanks, Neil! ~500 mins to wait now. Do I have to fear read-errors with RAID5 now? I still don't fully understand if there are also 2 bits of parity-informations available in a degraded RAID6 array on 2 disks only. Thanks again so far, hoping the best now ;-) Stefan
