I just got a 64gb card to rsync my hard drive on to How do I see what the card is listed as? (/media/bmike1/????)

This is the command I use:

      rsync -aWuq --delete-before /home/bmike1/Documents\
      /media/bmike1/<???>

I have two questions. I want to retain the dos format so to name it would I use the command 'dosfslabel' or would another be more approprialte?
  and
would I use the same command?
