Last week Jess Garcia asked me to be on a special webcast to briefly discuss volume shadow copies. Kristinn Gudjonsson also appeared on the webcast to discuss his log2timeline software.
If you want to watch/listen you can do so here: https://www.sans.org/webcasts/fighting-computer-forensics-93339 Remember that you’ll need to register with Sans to do this (its free of charge) and you’ll also get access to all of their previous webcasts.
If you want to sign up for the summit it is not too late. It is being held in London on April 19 and 20. You can find all the relevant information here: http://www.sans.org/eu-forensics-incident-response-summit-2010/
