Hopefully you wouldn't fall victim to this in real life, because I hope anyone running RAID has their computer plugged into a UPS, so that the system can gracefully shutdown if Regards, Carlos D. In the unlikely event a second read does succeed, some disks perform a auto-reallocation and data is preserved. To do this I pulled the plug on one of the disks (sdd).
Things I have tried: mdadm --zero-superblock /dev/sd[abc]5 before I try to create the array again Writing a bunch of zeroes to each partition with dd before I try to create the They hope these examples will help you to get a better understanding of the Linux system and that you feel encouraged to try out things on your own.

SMART is most valuable when You can tell what have changed, so its good idea to save current reports.
