Cannot transfer large folders from external HD to MBLD

Like many I’m experiencing agonisingly slow transfer speeds for files with my MBLD.

For instance, copying my iPhoto library to shared photos - after the progress bar indicated I needed 64 days(!) to transfer a 70 gig folder I tried a different tactic.

I copied the folder from my MacBook to another external hardrive (didn’t take 64 days) I then plugged the external hard drive into the MBLD and tried to drage the folder across.

This just led to my MacBook beachballing non-stop. Any ideas why I’m having problems with this?

I’ve got a 2008 MacBook running Mountain Lion, although I’ve also tried using my work computer - a 2012 MacBook pro running Lion.

Amy help greatly appreciated.
