Which tool is often used for disk imaging in forensic investigations?

FTK Imager is a widely used tool for disk imaging in forensic investigations due to its ability to create exact copies of digital media, ensuring that the data is preserved in a forensically sound manner. This tool can capture images of hard drives, USB drives, and other media while maintaining the integrity of the original data, which is crucial in legal and investigative contexts.

The capabilities of FTK Imager allow investigators to access the data within the images created without altering the original content, which is fundamental in forensic practices. It supports various file formats and provides features such as file carving, previewing files, and generating hash values for verification, all of which are essential in forensic analysis.

While write blockers are important for preventing changes to the original device during imaging, they are not imaging tools themselves. Wireshark is a network protocol analyzer and is primarily used for monitoring and analyzing network traffic, not for creating disk images. EnCase is another forensics tool that can create disk images, but FTK Imager is specifically recognized for its imaging capabilities, making it the chosen answer in this context.
