If you like, you can use my bash script for that purpose. It actually does a little more than you need, i. e. it will also show how much space is used. Hope you like it :) And I also hope that the output will be as neat as on my linux box... (Note: it will only show real hardware like your HDDs and DVD-ROMs, but that's sufficient for my purposes.)

Important note: On Ubuntu and flavors, this script might have to be run under sudo ONCE because of blkid. At least on my distro, blkid -o export will output nil when run as regular user after bootup. As far as I've learned, the "regular user version" of blkid will retrieve output from cache, and to populate the cache with data, a run under sudo is required on a couple distros.
