Minecraft – Do drives fragment, and if so is there a way to defragment them automatically

Here's an elaborate solution involving trapping a skeleton that appears to work well. It seems that this setup could easily be changed to use a snowball/arrow dispenser instead of a skeleton, however the business of keeping it fueled, and firing at the right time would be an issue.

I don't know the definition of tree miller...

[EDIT: as the video I linked to disappeared, thank Robotnik for pointing this out]

But there are a variety of semi-automated tree harvesters out there that are capable of a modest amount of AFK.

The idea is for you to have saplings in your hand, plant one, have a bone meal dispsenser adjacent, which bone meals the sapling.

Once the sapling grows into a tree, a large redstone device, which surrounds a 5x5 area pushes the logs out to a large wood collection area.

If you are daring, you can build an enclosure for a wither, and have the wither blow up the wood, most of which will get harvested.

Saplings are collected in hoppers at the bottom, and moved back to you, so you just have to sit and plant saplings.

There are many tutorials on the topics, in particular, google: Minecraft automatic tree farm (or minecraft AFK tree farm). A video from a more famous youtuber than previously posted is here:
