Ah, right.  I've just found a few ways:

havoc:cjb~ % sudo smartctl -d ata --all /dev/sda
=== START OF INFORMATION SECTION ===
Device Model:     HDT722525DLA380
Serial Number:    ...

havoc:cjb~ % sudo hdparm -iI /dev/sda
ATA device, with non-removable media
        Model Number:       HDT722525DLA380                         
        Serial Number:      ...

I also found http://linuxbasics.org/tutorials/using/using_udev , which
mentions using the serial number of USB disks to let your machine's udev
know where they should be mounted each time.  Neat!

- Chris.
