As root mount your external drive like:
# mount -t <your-filesystem> /dev/<your-device> /var/ftp/uploads
The original contents of /var/ftp/uploads remain intact (if there are any), but as long the drive is mounted the drive contents will be accessed.
Or add something like
/dev/<your-device> /var/ftp/uploads <your-filesystem> rw,user,auto 1 2
to your /etc/fstab file to automatically mount at boot time.
