It was surprisingly quite simple, and it worked.

Firstly :

I installed the new HDD as secondary master.

I then created all new partitions on the new HDD, but I made them 
considerably larger than the originals.

I then used dd to copy each of my older partitions across to the new drive, 
this was rather slow - so I let it run over night.

I then swapped the cables of the drives - making the newer HDD the primary 
master and the older drive was then relegated to secondary slave.

I then used a knoppix live CD to boot the system - navigated to the new 
/boot directory and simply ran the command to install grub to the primary 
hard drive.

#grub-install /dev/hda

Rebooted the system and continued using Linux as if nothing had changed.

It all appeared to be "too easy" but it worked.

NOTE : It will only work if all of the grub files are located in the 
correct directory locations under /usr/lib/grub/i386-pc. 

If you do not have these files in the correct location - you will need to 
refer to section 3.3 of the "GNU GRUB Manual 0.97" - available in pdf 
format. 

The Grub installer may have problems with some BIOS' mapping of drives so 
you need to know how to specify any arguments required.

I guess I got lucky - it worked first time.
