We already had code for this, see:
2009-09-05 Robert Millan <rmh.g...@aybabtu.com>
* util/grub-probe.c (probe): Comment out buggy codepath, which
was unexpectedly enabled by Colin Watson's 2009-09-02 fix. This
should be re-enabled after 1.97.

Unlike the filesystem driver, grub-probe already knows we want to probe for
a file. Then this assumption won't be necessary.

still allow you to remove your data and not access it at all."
