"/media is another interesting folder, as when you plug in an
external hard disk or a USB key or similar this is where will show
up. Devices are assigned a sub-folder which is derived from the
device's name. I have specially named all of my devices, so that
when I plug in my external hard disk it shows up as /media/IDE320
or /media/SATA750 or /media/USB2GB. DVD and CD devices can be found
here, but often they'll show up as a desktop icon too."
