Back to square one and re-dd original to test drive
and start over.
Ouch! That _used_ to work. Trying it just now, "mke3fs -S" seems
to clear a substantial portion of the inodes, which the manpage
specifically says it should _not_ do, and then /fsck/ completes the
destruction by moving all of the remaining inodes to lost+found.
Sorry about that.
Can raise a bug against it?
Chances are this is an upstream bug, or a misunderstanding. You
should post your reproduce steps to the ext4 list, what you expect to
happen based on man page, and what actually happens.

It might be better for someone besides me to do that. I'm running an
RHEL 6 clone, which uses e2fsprogs-1.41.12. If I post on the mailing
list I'll immediately be told to upgrade to the latest version. Since
my ox is not the one being gored here, I'm reluctant to jump through
the hoops needed to do that.
/ posted it to the ext3 maling list (turns out they also know ext4)
and they admitted about undocumented effects of using the -S
option, and that one must NEVER use it unless they know the intrinsics
of the FS so well, that the user knows exactly what effects it will
have.
