This would be good provided the black box remains where the ship was destroyed elseways the less than scrupulous explorer can use data preservation as a quick way to suicide back from a long trip.
That's one potential exploit (of protected data) that results from dead not being dead in the game, even if you die on the edge of the galaxy, far from a 'resurrection ship'. Loss of that data discourages this, but at the expense of griefers cleaning you out anyway, for no financial gain. There's no perfect solution. I failed to mention that scanned ships would give off an audible warning if they were storing lots of data. Even that wouldn't deter everyone. The game just isn't balanced to make exploration a prized, protected, activity.
