Very good piece of information to have here.

I'd locally tweak (read: no need to resend) it to
Use `dd bs=1048576 count=101`, which ...
and downcase "Call" on the title line.
A tangent. I wonder how portable
dd bs=1024x1024 count=101
dd bs=1kx1k count=101
are in practice. "Two or more positive decimal numbers (with or
without 'k' or 'b') separated by 'x', specifying the product of the
indicated values" is from POSIX, but I haven't used it myself (I
know GNU dd groks it).
In any case, thanks for the update.
