Software forensics tools typically copy data from a suspect's disk drive into which type of file?

• A. A plain text file
• B. A log file
• C. An image file
• D. A backup file

Answer: (C)

Creating a bit-for-bit disk image preserves the suspect's drive contents precisely. Forensic tools copy the entire disk, including every sector, unallocated space, and metadata, into a single image file so analysts can examine it without touching the original evidence. This image can be hashed to verify integrity and supports repeatable analysis, which is crucial in legal contexts. Plain text files can’t hold binary data and would corrupt many sectors; log files only record events, not the raw contents; and backup files aren’t guaranteed to be exact sector-for-sector copies and may alter data through compression or metadata. Therefore, the appropriate format is an image file.
