What is the significance of MFT entries in forensic analysis, and how can deleted files be recovered when their records have not been overwritten?

• A. The MFT only stores file creation times; cannot recover data.
• B. MFT entries store file metadata and data attribute runs; if not overwritten, deleted files can be recovered by analyzing MFT records and data attribute runs; use carving or metadata analysis.
• C. MFT entries are irrelevant for deleted files; only the data bytes matter.
• D. MFT is for drive health and not for forensic.

Answer: (B)

MFT entries are central to NTFS forensic analysis because they hold the file's metadata and the pointers to where its data actually resides. A deleted file isn’t instantly erased from the disk; the MFT record for that file is typically marked as deleted, and the data clusters it references may remain on disk until overwritten. If those records have not been overwritten, you can use the MFT to learn the original file name, timestamps, and other attributes, and you can follow the data attribute runs to locate the exact clusters that contain the file’s bytes. This makes it possible to recover the file contents and reconstruct the file even after deletion, often without needing to resort to blind data carving.

In short, the MFT provides both the map (metadata and data pointers) and the means to assemble the file, so its persistence enables recovery as long as the underlying data regions haven’t been overwritten.
