<title>Wipe everything off a removable disk</title>
24
<p>If you have a removable disk, like a USB memory stick or an external hard
25
disk, you may sometimes wish to completely remove all of its files and
26
folders. You can do this by <em>formatting</em> the disk - this deletes all
27
of the files on the disk and leaves it empty.</p>

<title>Formatting a disk does not securely delete your files</title>
71
<p>Formatting a disk is not a completely secure way of wiping all of its
72
data. A formatted disk will not appear to have files on it, but it is
73
possible that special recovery software could retrieve the files. If you
74
need to securely delete the files, you will need to use a command-line
75
utility, such as <app>shred</app>.</p>
