Yes, thanks.  I think I will have to write a cron job.

One problem I have now is that the two USB disks are mounted with different
permissions.  I've abandoned mounting them with fstab, so they are now
mounted automatically in /media/<user>/  but the new disk is mounted with
root as owner and group and I can't write to it (create folders etc).  The
old disk however, is owned by me (group is users).  Why should they be
different? And how do I make it so that they are both always mounted so
that I can write to them?
