According to the CHFI v11 objectives underData Acquisition,Digital Evidence, andImage/Evidence Examination, forensic investigators must be able to work with different disk image formats. TheE01 format(Expert Witness Format) is widely used in digital forensics because it supports compression, metadata storage, and integrity verification through hashing. However, many Linux-based forensic tools require the image to be mounted or accessed in araw (dd) formatfor direct analysis.
ewfmountis a Linux utility from thelibewftoolkit that allows investigators tomount E01 (and other EWF) images as raw disk images. Once mounted, the image appears as a raw device, enabling investigators to analyze partitions, file systems, and artifacts using standard forensic tools without altering the original evidence. This approach preserves forensic integrity and aligns with CHFI v11 best practices.
Autopsy (Option B) is a forensic analysis platform but does not perform E01-to-raw mounting itself. UFS Explorer (Option C) is a commercial forensic tool used for file system analysis, not image conversion. fdisk (Option D) is a disk partitioning utility and cannot mount or convert forensic image formats.
