But now, I cannot mdadm --assemble the array. It says : mdadm: no RAID superblock on /dev/sda mdadm: /dev/sda has no superblock - assembly aborted Is it possible to assemble this array because I don't want to lose my data... Someone told me that I can do a : mdadm -Cv /dev/md0 -l5 -n5 /dev/sda /dev/sdb /dev/sdc /dev/sdd /dev/hdc But if do that, all the data on the raid will be lost or not ? Is there an other way to get back these data ? Thank you very much for your help. -- Raph.
