Final answer:
Unallocated space is not captured during a logical disk imaging process, potentially leading to missed data. Forensic disk imaging is necessary to include both allocated and unallocated space for a complete duplication of a drive.
Step-by-step explanation:
Unallocated space is typically not captured during a logical disk imaging process, potentially resulting in data being missed. Logical disk imaging is a process that involves capturing a copy of the filesystem structure, including files and folders that are visible to the operating system. However, unallocated space, which can contain residual data from previously deleted files, is not usually included in such an image because this space is not part of the active file allocation table. To capture everything, including unallocated space, a forensic disk image must be created. A forensic disk image is a bit-by-bit copy of an entire drive, including all the allocated and unallocated space, ensuring that all potential evidence is preserved.
