  • Yet another live image carrying both dc3dd and dcfldd: en.altlinux.org/Rescue (it's also careful enough not to touch dirty filesystem journals and swaps).

  • Nice work ! Great project.

  • Love that its free

  • If anyone is looking for a pre-built self booting solution on a USB drive to run dc3dd, you can fine on here, www.osforensics.com/tools/create-disk-images.html

  • in our tests, DC3DD is about 20% faster than the older dcfldd. however, they changed a lot of the options, and it was confusing trying to associate the new options with the older dcfldd options used in our scripts. output logging could be enhanced to be more easily processed by additional scripts.
