Which tool is a command-line disk acquisition tool from New Technologies, Inc.?

SafeBack is recognized as a command-line disk acquisition tool developed by New Technologies, Inc. This tool is specifically designed for acquiring disk images, providing features that facilitate the creation of exact copies of storage devices, which is essential in digital forensics for preserving evidence without altering the original data.

In the context of digital forensics, command-line tools like SafeBack are critical because they enable precise control and scripting capabilities, allowing forensic investigators to automate processes and ensure consistency in evidence acquisition. The use of command-line interfaces can also enhance the efficiency of handling large volumes of data or when performing repeated tasks across multiple systems.

While options such as DiskDigger, ImageX, and FileCarver serve important functions in the realm of digital forensics—such as data recovery, creating Microsoft disk images, and carving files from unallocated space, respectively—they do not fall under the category of command-line disk acquisition tools from New Technologies, Inc., making SafeBack the most suitable answer for this question.
