I've written a couple of simple overviews of the issues surrounding dd and the seeming lost sectors when bad blocks are encountered. I neglected in my previous posts to include a link to the research by NIST at http://dfrws.org/2007/proceedings/p13-lyle.pdf.
Speaking to both Drew Fahey and Barry Grundy the feeling is that there is no reason to overreact, virtually every tool we use has some flaw or another, however further research is needed to be clear about the issue and how to circumvent it.
I'm off to present at the ACPO conference tomorrow and I'm sure the subject will come up, I'll post any interesting comments.
