Why not just attach the first hard drive you copied to to a computer along with a second new hard drive and copy the files from the first to the second? This will be much faster than copying from the camcorder again anyway.
Why is copying a second time from the camcorder directly to a second drive so important when this alternative is easy? I'm sure you are aware of this alternative, so what is the point (I understand why you might want the same files on two hard drives)?
