(7) reinserted disk (and rebooted)
    At some point before reboot the first 10 sectors of one disk
    were zeroed to test if the disk gets removed from the btrfs.

IIRC the superblock is not placed at the beginning of the disk. On
the basis of [1] it should be near the 64KB (around the sector #128)

   Just for the record, the first is at 64KiB; each subsequent one is
shifted 12 bits left (256MiB, 1TiB, 4EiB, 16ZiB, 64YiB).
