You are missing one 'dd' from the other system side, but
are you also sure that the remote system can support large
files, and that the dd in there does support large files ?

Verify that you can 'dd if=/dev/zero of=/dev/sda2 bs=1M'
at that remote system -- then we know that dd in there
(and the system) can do it, and the bug-sphere shrinks.

There should not be anything such.
(But of course things like RSH could have some nasty surprises
in them...)
