What command are you using to copy this data? Try:

rsync -av /source/ /destination/

and see if you get any output when it fails. There have been other guesses,
but with the information you've provided, that's all we can do. My "guess" is
you're using cp and it gets to a large, corrupt file and fails.

Post back with your command and it's output, then the rsync command above and
it's output; as well as the inode command Dale gave you, and any other
applicable commands you've had suggested.
