What I know for sure is that now, I get this: user@host:~$ sudo mdadm --examine /dev/hda1 mdadm: No super block found on /dev/hda1 (Expected magic a92b4efc, got 00000000) user@host:~$ sudo mdadm --examine /dev/hdc1 mdadm: No super block found on /dev/hdc1 (Expected magic a92b4efc, got 00000000) user@host:~$ sudo mdadm --examine /dev/hde1 mdadm: No super block found on /dev/hde1 (Expected magic a92b4efc, got 00000000) user@host:~$ sudo mdadm --examine /dev/hdg1 mdadm: No super block found on /dev/hdg1 (Expected magic a92b4efc, got 00000000) user@host:~$ sudo mdadm --examine /dev/hdi1 mdadm: No super block found on /dev/hdi1 (Expected magic a92b4efc, got 00000000) I didn't format the partitions or write any data to the disk, so I think the array's data should be intact. Is there a way to recreate the superblocks, or am I hosed? Thanks, Neil
