    you mean -N ?

    Indeed. That prints the superblock backups. Nice option.

    I was able to dd if=/dev/ad2s1e without any errors (funny that the
    fsck says it cannot read lotsa blocks).

    I moved that (10GB) dump to another machine where I might
    mount it on a virtual device and perform further recovery measures.

    Any ideas how to proceed?
