Which Linux utility is commonly used to create forensic disk images?

The utility used to create forensic disk images is often DD. It is a powerful Unix command-line tool that allows for the low-level copying and conversion of raw data from one location to another. In the context of digital forensics, DD is particularly valuable because it can create exact byte-for-byte copies of a hard drive or disk partition, preserving the integrity of the data.

This function is crucial in forensic investigations, as it allows practitioners to analyze the copied data without modifying the original evidence. Furthermore, DD can support various file formats and compression methods, making it a versatile choice for forensic imaging tasks.

Other options listed do not serve the same primary purpose in forensic imaging. For example, EXIF is primarily used for handling metadata associated with image files rather than creating disk images. Diskcapture and Diskcopy may refer to other utilities but do not hold the same widespread recognition or application in the forensic community as DD does. Thus, DD stands out as the most appropriate and widely-used utility for creating forensic disk images.
