Shardana Antivirus Rescue Disk Utility (SARDU), is a multiboot disk creator that you can use to create a customized toolkit of your favorite bootdisks, live CD antivirus tools, and more. SARDU is a simple menu-driven app that lets you choose from a menu of antivirus, partition managers, data recovery tools, bootdisks, and OS installers, download the relevant ISOs, and then create a bootable disk loaded with your own custom software package.
Verdict: An interesting piece of software that allows you to customize your own rescue disk, putting a host of your favorite recovery tools onto a single thumb drive. Obviously only as good as the software you choose to burn onto it, but the selection is quite good.
Note: SARDU will offer to install extra toolbars, change your homepage, and your default search engine, so be wary during install.
