All you're missing is the command line.

First, run "df -h" to ensure that the drives are mounted
properly and appear to have the right amount of free
space.

Next, run "ls -ld" for each of the mountpoints.  Verify
that the permissions are right.

Then use rsync to copy the files.  Something like:
rsync -aHvx --progress /mnt/nas/ /mnt/hdd

That should do the trick.  Let us know how it goes.
