Analog Hard Disk 2 assembling instructions
updated PCB can be seen here:
there are allot of different hard disks and they all sound a bit different.. connecting them up will also be different for them. some are easier then others.
you can find the connection point for the hard disk arm (the red and the blue wires in the picture) by looking for the connection strip between the arm and the base plate. there is this orange plastic strip with metal traces in it.. on this strip look for the biggest traces and try to see if the go to the coils in between the magnets.. if they do follow them back to where they come from and you will find 2 connections points you can solder the red and the blue wire to.
to find the connections from the hard disk wheel, look for 4 connection traces that come from the center of the wheel.. or for 4 connection points on the backside of the hard disk.
solder the 4 green wires to these connection points.. it does not matter in what order.
