&gt; 
&gt; (A big part of computer forensics is the recovery of deleted files and
&gt; file fragments, so there is a lot of relevant info in this paper.)
&gt; 
&gt; The first third of the above whitepaper is basic linux stuff that most
&gt; people on this list know.  (Thankfully, tac is introduced in a latter
&gt; section.  I don't feel quite so ignorant.)
&gt; 
&gt; The other 2/3's are more interesting.  It could be the basis of either a
&gt; detailed computer forensics presentation, or data recovery.  (For data
&gt; recovery, you could just leave out some of the steps like calculating
&gt; the md5sum of the raw disk before and after making a working copy.)
&gt; 
&gt; I know there was a computer forensics presentation last summer, but it
&gt; was more conceptual with references to tools and their functionalities.
&gt; 
&gt; The above goes into actual command-line parameters, etc.  I have only
&gt; scanned it so far, but I think it would make an interesting basis for a
&gt; presentation.  (In particular it has 10 pages dedicated to autopsy, a
&gt; gui environment.)
&gt; 
&gt; I think it even has some disk images online that can be analysed and
&gt; files recovered.  The presentation could include some actual recoveries
&gt; from the sample.
&gt; 
&gt; I have never used linux to do data recovery, but if you don't have any
&gt; other takers I would consider giving the above a shot.
