The Dink Network

Alright, so I'm finally getting back to doing something to my dmod after a year or whatever, and I need some help with the tiles. Now, I was a fool, so I edited just random tiles' hardness, to shape around my houses, but it messed up other stuff, so i just foolishly went around applying this tile hardness here, and another there, it's pretty bad. So I come and look at the stuff here, I see Redink1's rewrite, so I can use that to get back to the original tile hardnesses, and now I have a list of what I should edit this time around, and what to leave.

My question:
Is there a good way to apply all the original tile hardnesses? Is there any good way to get all of the tiles to revert back to their originally applied number? Not sure if this makes much sense, but basically now I have random hardboxes all over the stuff, and I want to just start it all over, but if I delete the hard.dat, I just lose everything. Obviously, I'll still have to edit what I want around houses and so on, but just seeing what I can do as opposed to going through and applying the 0 hard tile to all the spots...
