Why can't you mount the disc on /mnt and then use tar after mounting the disk to copy the files from /mnt to /destdir ...

tar cpf - -C /mnt . | tar xvpf - -C /destdir

That will preserve hard links, symlinks, permissions, and times (and doesn't require rsync).

There are other methods involving cpio, but I find tar to be nice.
