Alright, so I got a Twin Famicom and 8 games. When I first had it two worked and the rest didn't, so after reading about I figured it was probably the belt. After following a tutorial and having bought a belt online I cleaning out the old one and got this new one.
This still led to the same problem. I then used a head adjustment tutorial from jfgoods and this got all the other games working but now the original two that did do not :-/
After reading some pretty old threads this sounded kinda promising:
Well folks, I fixed about 3 dead drives already. I replaced the belts and I had to adjust the motor and the head to get them working. There is actually a method that works to perform this.
1. Change the belt. I also used JF Good's belt.
2. Tune the motor all the way down! I believe it is counter clockwise (just look for the negative sign on the motor and adjust that direction). This is the real trick! All three drives I had to adjust the motor to run slower.
3. Now adjust the heads.
So, the errors really tell you what's going on.
a. When you turn the head adjustment screw, the trick is to get it right at the beginning of the disk track. So, if you see an Error 21 "Disk Header block (NINTENDO-HVC*) part is wrong", 22, "Disk Header Block Recognition isn't read and can't be ignored", this means that you are "BEFORE" the beginning of the header track. You need to adjust the head forward until you finally read the disk. This takes time. You basically have to keep loading a disk until you see the FDS game boots up. It is a great feeling when you see it!
b. If you adjust the head forward too much, you get a Disk Error 27, "Block end mark seen and ends prematurely". Or even Error 28, 29. Turn it back to the beginning until you get the error 21,22s.
I have been using this methodology for 3 FDS and I fix them everytime if the belt, motor adjustment, and alignment are the problem. If you have any electronics problems then you are SOL.
So, I have given everyone the secrets to adjustment and it really is not a secret anymore!
If you have a broken drive and you need it fixed, PM me. I can probably take a look at it. Anyway just PM me.
Good Luck and let me know if my methodology works for you.

So any advice to what I should do now? Or does anyone know what he means by "The head" in this description and how do I move it forward? I'm pretty determined to get this thing working but I don't really understand what's going on in this tutorial.
