Lightroom

I have been using Lightroom on my Vaio for a long time. I have a bunch of small (they were big at the time) USB hard drives with tons of images on them. The Mac is THE machine for images and graphics, right? So I bought a new 500 Gbyte Firewire drive and decided to consolidate all of my images on the new drive using Lightroom (latest version).

So I connected the Firewire drive and the first of my USB drives and started a new catalogue in LR and proceeded to copy all of the images from the USB drive to the new Firewire drive. After 4 hours or so I figured out Lightroom was "not responding" tried force quit and the computer completely hung I had to do a hard restart. Still trying to copy the files . . .
