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.
