From the Introduction: "The objective of the CFTT [Computer Forensics Tool Testing] program is to provide measurable assurance to practitioners, researchers, and other applicable users that the tools used in computer forensics investigations provide accurate results. Accomplishing this requires the development of specifications and test methods for computer forensics tools and subsequent testing of specific tools against those specifications. Test results provide the information necessary for developers to improve tools, users to make informed choices, and the legal community and others to understand the tools' capabilities. [...] This document reports the results from testing the disk imaging function of CFT [Computer Forensic Tool] Version 3.4.1 using the CFTT Federated Testing Test Suite for Disk Imaging, Version 2.1."
