Just to add a bit to what Polytropon has explained already:  If this
means that you expect to see the file
FreeBSD-11-RELEASE-amd64-memstick.img on the USB stick, then there is a
problem.

If you actually see a file with that name, you've done something wrong
and there is no way it will boot.

If you expect to see the file, then you don't understand what is
happening and should pay closer attention to what several people have
already explained.

The file FreeBSD-11-RELEASE-amd64-memstick.img is a sequence of bytes
which are kept in a file because that makes it possible to retrieve from
an HTTP or FTP server, and to save locally.  However, as far as the USB
stick is concerned, it is a long stream of bytes, which must be written
to the USB stick starting at the first location on the stick and
continuing in strict order until all the bytes are written.  This is why
you use the dd command, which does that, rather than the cp command,
which thinks in terms of copying files. Which is not what you're doing.
Or at least not what you should be doing.

As an aside, as I've read this sequence of e-mail threads with some
bemusement over the past couple of days, I've formed the impression that
you seem to put more energy into reporting what you think should be
happening rather than accurately reporting what you did and what
resulted.  At your stage of enlightenment, it is probably more efficient
to prioritize differently.

And explaining to somebody with vast experience and considerable more
patience than I that he's wrong about "1M" because "1m" doesn't work
really, truly is a waste of everyone's time.  Unix is [mostly] case
sensitive.
