  • Creating a dd/dcfldd Image Using Automated Image & Restore (AIR)

    Author: dream1600Tags: , Comments: 8

    Creating a dd/dcfldd Image Using Automated Image & Restore (AIR) Automated Image & Restore (AIR) is an open source application that provides a GUI front end to the dd/dcfldd (Dataset Definition (dd)) command. AIR is designed to easily create forensic disk/partition images. It supports MD5/SHAx hashes, SCSI tape drives, imaging over a TCP/IP network, splitting images, and detailed session logging. To date, the AIR utility has only been developed for use on Linux distributions. In its simplest form, AIR provides a convenient interface to execute the dd set of commands. It eliminates the risk of "fat fingering" an error in the shell terminal and ultimately makes using the dd command more user-friendly for those who are not as experienced. Please note that using the AIR front end still requires some basic knowledge of how the dd (or dcfldd) commands work.
