Of course the test is very simple. I am trying to simulate physical damage
of disk surface. It is simply a scratch leading to several damaged tracks.

That is the problem. The ext2/3 inode tables are spread in all block
groups across entire disk. And damaging several continuous tracks doesn't
result in such a big data loss.
