Copying files but stuck on 0% remaining?

buyitall

Long story but ....I am copying files from one portable hard drive to another, in order to give me a blank portable hard drive that I can use to make an image of my internal hard drive before replacing it. There were loads of files to copy, so it has taken 2.5 hours, but has now stuck on 0 secs remaining! If I click on 'cancel' now, will I lose the whole copy? (I intended to 'copy' first and then delete the files on the postable hard drive once I was sure they had copied. Both portable hard drives had about the same amount of data on them originally).
Thanks for any advice, it has been stuck on 0 seconds for about 30 mins now.

try copying first to a computer, then from there copy to said PD //

Thanks, presumably that will take another 5 hours! Is there a quicker alternative?
