Fully Functional 1KB Hard Drive in Vanilla Minecraft

This will not work as described. I think his design is a good idea, but still does not work.

I build a better harddrive (with 4 kb storage!) over a year ago, imgur link will follow.

Now to the design problem in this HDD: see that all the blocks are blue in the platter? No way to swap each of the bits without magically creating new green blocks. My hdd solves that problem by having BOTH block types available on the platter. But see for yourself:

How confident are you?

I know very little about Minecraft, but if this doesn't work, it pretty much has to be trolling. (No way you build something like this and not notice that it doesn't work.) And then I wouldn't expect them to offer a link to download the map, and I wouldn't expect someone else to say they've got it working: http://www.reddit.com/r/Minecraft/comments/2e0ghk/fully_func...

ok, it does work. i totally forgot about the command blocks. he's using them to change the block type.

Imagine a write process: You'd need to somehow replace the visible blue blocks with a green block. But where does the green block come from?

I don't know much about MC or computers, but as far as I understand each bit has both blocks, shift up for blue=0, shift down for green=1. Here: http://i.imgur.com/rqZm4DU.gif

Yes, but you don't see BOTH block types on the big tape. Swapping bits requires one block for each state, but the green ones are missing from the tape screenshots.

I don't think that they have to necessarily be green. So the fact that you don't see them may not mean that they are not there. He may be using blocks the same color as the structure for aesthetic purposes.
