Why not fix? I wouldn't remove the test, just  relax it to


if ((sparespercyl + secspercyl) != (nheads * secpertrack)) {
	annoy_user_with_warning();
}

which makes more sense to me. All warnings I have encountered, including
the one now reported, fail the current test, but would pass the above
one.
