How does data carving differ from traditional file recovery?

• A. Data carving reconstructs files by searching for file signatures in unallocated space without relying on filesystem metadata, whereas traditional recovery uses filesystem metadata and records.
• B. Data carving requires filesystem metadata; traditional recovery does not.
• C. Data carving reconstructs files using only metadata.
• D. Data carving cannot recover deleted files.

Answer: (A)

Data carving focuses on extracting files by scanning the raw bytes for known file signatures and delimiters in unallocated space, without depending on the filesystem’s bookkeeping. It treats the drive as a continuous stream and uses headers and footers to determine where a file begins and ends, which lets you recover data even when the filesystem metadata is missing or damaged. Traditional recovery, on the other hand, relies on the filesystem’s metadata—things like directory entries, allocation maps, and file records—to locate and reconstruct files. This approach can preserve original filenames and directory structure when the metadata is intact and usable. So the key difference is that carving works independently of the filesystem's records and can retrieve data from areas not tracked by the filesystem, while traditional recovery uses those records to piece together files. Carving is powerful when metadata is corrupted, but it may struggle with fragmented files or lose naming information, whereas traditional recovery can be more precise and contextual when the filesystem is healthy.
