I am a little disappointed with the recent release of Helix. I've been using the CD for quite some time now, and the new version has a couple of annoyances to me:
1. New build based on Ubuntu. I have had some issues getting the disc to boot with some systems. Ubuntu seems to be less forgiving when it comes to hardware. I carry around version 1.9a and the new version.
2. There is now an option to Install Helix to Hard Drive. I realize that this could be cool, but I think its a dumb option on a forensics CD that is supposed to not modify original evidence. How many people who aren't familiar with evidence handling rules and Helix will attempt to install the software onto a drive they are attempting to analyze?
3. The disc mounting and formatting is still confusing to a novice Linux users. Many forensics investigators do not have Linux ops training. They are only familiar with the OS from an investigative point of you. Many of my coworkers are switching to RAPTOR, which makes this task much easier for them.
