Better late than never!
Version 9.04 (Jaunty Jackalope) of the very best Free-Libre Open-Source data recovery software toolkit based on Ubuntu is out.
This release of Ubuntu-Rescue-Remix features up-to-date versions of the most powerful free/libre open-source data recovery software including GNU ddrescue version 1.10, Photorec, LVM2, etc...
You can download it here:
This iso image is compatible with the excellent USB Startup Disk Creator that is included with Ubuntu since 8.04 (System - Administration - USB Startup Disk Creator). Use it to put the Rescue Remix along with a persistent home on any USB flash drive.
The live Remix provides a full shell environment. If you prefer to work in a graphical environment, a metapackage is available which will install all the data recovery and forensics tools onto your current Ubuntu system. To do so, add the following archive to your software channels:
deb http://ppa.launchpad.net/arzajac/ppa/ubuntu jaunty main
Then, install the "ubuntu-rescue-remix-tools" package.
If you want to expand the Rescue Remi's capabilities and features, please join in its development. Any and all help is welcome!
