I have heard about a system, I believe used on DDS (4mm) tapes where
the drive writes a special signal on the tape when it stops writing,
and will refuse to pass that signal on reading.

One solution I have heard used is to start writing at EOT,
and then power down the drive before it has a chance to write
the special EOT mark.  A similar system may work on other
drives, but it risks some of the data after the EOT.
