It returns a list of the storage devices on the system. For example:

<div class="tip">
<p>If you are unsure about the path to the USB image, you can insert the
correct path by dragging and dropping the icon of the USB image from
<i>Finder</i> onto <i>Terminal</i>.</p>

<p>You can try adding <code>r</code> before <code>disk</code> to make the installation faster.</p>

You should get something like this:

If no error message is returned, Tails is being copied on the USB
stick. The copy takes some time, generally a few minutes.

<div class="note">
<p>If you get a <code>Permission denied</code> error, try
adding <code>sudo</code> at the beginning of the command:</p>

<p>If you get an <code>invalid number ‘16m’</code> error, try
using <code>16M</code> instead:</p>

The installation is complete when the command prompt reappears.
