    <title type="html"><![CDATA[Securely erasing old hard drives]]></title>
    <summary type="html"><![CDATA[<p>As you know, when you are about to discard or recycle a computer, you should securely delete all the data from them.  Just formatting them is not enough.
</p>

<p>Shredding takes a long time, so be prepared and patient.
</p>
<h1 class="showhide_heading" id="Linux">Linux</h1>
<p>On Ubuntu/Linux, it's a breeze.  Just use shred.
</p>
If the drive is still in the old computer, boot from an Ubuntu live CD, the run shred on the hard drives.  First, use <pre class="codelisting"  data-wrap="1"  dir="ltr"  style="white-space:pre-wrap; white-space:-moz-pre-wrap !important; white-space:-pre-wrap; white-space:-o-pre-wrap; word-wrap:break-word;" id="codebox1" >sudo fdisk -l</pre> to find out the names of your internal hard drives.  Then, run shred like so:<pre class="codelisting"  data-wrap="1"  dir="ltr"  style="white-space:pre-wrap; white-space:-moz-pre-wrap !important; white-space:-pre-wrap; white-space:-o-pre-wrap; word-wrap:break-word;" id="codebox2" >sudo shred -fvn 3 /dev/DRIVE</pre>
<p>
</p>
<h1 class="showhide_heading" id="Windows">Windows</h1>
<p>On Windows, it was a little harder.   I had a couple of computers that couldn't boot from my Ubuntu Live CD.  So I removed the hard drives from the old computers and then attached them to this USB device that connects to my new Windows 7 laptop (ThinkPad Edge, from David Dion at Brick Computers in Ipswich, MA).
</p>

<p>I tried to use shred or srm on cygwin but I couldn't find them in the cygwin repository.
</p>

<p>I found it easiest to do a Quick Format of the drive first.  That way you don't have to worry about the difference between shredding files vs. free space.
</p>

<p>Heidi's Eraser had permissions problems that I couldn't (bother to) resolve.
</p>

<p>I then found a reference to the "cipher" command on the web.  Cipher has apparently been included in Windows for a very long time.   Here's my command in Cygwin:
</p>
<pre class="codelisting"  data-wrap="1"  dir="ltr"  style="white-space:pre-wrap; white-space:-moz-pre-wrap !important; white-space:-pre-wrap; white-space:-o-pre-wrap; word-wrap:break-word;" id="codebox3" >$ cipher /W:D:\\
To remove as much data as possible, please close all other applications while
running CIPHER /W.
Writing 0x00
......................................................................</pre>
<p>Cipher does the "Writing" with 2 different characters and then a random series of characters (I think).   The problem I have with cipher is that it is fairly cryptic--it really isn't very explicit about what it is doing, and seems to be an add-on to an app that has different functionality.
</p>

<p>SDelete from Microsoft Sysinternals seems like a good tool.
<br /><a target="_blank" class="wiki external"  href="http://technet.microsoft.com/en-us/sysinternals/bb897443.aspx">http://technet.microsoft.com/en-us/sysinternals/bb897443.aspx<img src="img/icons/external_link.gif" alt="(external link)" width="15" height="14" title="(external link)" class="icon" /></a>
<br />My version of the SDelete.zip file download had sha256sum 0984beba7a5229f94d04dc62a5a48c36ce4483d1315356593d86fd741e365fb4
</p>

<p>You should always check your hashes. Someone could have switched out the file with a hacked version. Heck, my version could have been hacked, because I Googled that long hash and it didn't appear on the web anywhere.  So, I calculated the md5sum hash 012185d160417881a0ae92ded64f08d0   and found that in a couple of Asian websites--not very satisfying, but that's all we got.
</p>

<p>The website states:
</p>
<pre class="codelisting"  data-wrap="1"  dir="ltr"  style="white-space:pre-wrap; white-space:-moz-pre-wrap !important; white-space:-pre-wrap; white-space:-o-pre-wrap; word-wrap:break-word;" id="codebox4" >SDelete implements the Department of Defense clearing and sanitizing standard DOD 5220.22-M, to give you confidence that once deleted with SDelete, your file data is gone forever.</pre>
<pre class="codelisting"  data-wrap="1"  dir="ltr"  style="white-space:pre-wrap; white-space:-moz-pre-wrap !important; white-space:-pre-wrap; white-space:-o-pre-wrap; word-wrap:break-word;" id="codebox5" >C:\Users\Downloads\SDelete&gt;sdelete.exe -p 3 -z D:

<br />They say TrueCrypt could work to encrypt the whole hard drive, but I'll have to look into that later.
