Moving all my images to an external hard drive - a painful process! Update 3

Looks like I underestimated the scale of the problem. 

Copying my pictures folder over onto my external drive. 

Nothing wrong with that - makes perfect sense. All I do then is point Lightroom to the new location. Oh yes and try to make another copy of my pictures onto my smaller hard drive - this is the thing that didn't work earlier but I might just wipe it clean and start again.

And that is it. Job done. 

One small problem.
