Hi Neil Thanks very much for the help and advice.. Output as follows. [root@desktop mdadm]# ./mdadm --assemble --force --verbose /dev/md0 /dev/sd[abc]1 /dev/sd[defgi] mdadm: looking for devices for /dev/md0 mdadm: superblock on /dev/sdf doesn't match others - assembly aborted Maybe there has been some differences in Data Offset and superblock sizes with different versions of mdadm. I am not really sure what to do now, I just got back from a long project overseas and was about to start looking deeper into my options. Appreciate any further help or advice that you have.
