Figure 9, showing the hard drive assembly. Please note the picture shows the CD drive removed (on top of the hard drive) this operation can be completed without separating these assemblies.
Remove the three screws from the left hand side of the hard disk assembly. With the hard disk/CD drive assembly positioned as in figure 9 remove the first two screws from the
right hand side. Manoeuvre the assembly so as to remove the final screw from the right hand side. This one is a real pain. Do not disturb the ribbon cables!!
The hard disk assembly can now be removed from underneath the CD drive.
