In raw data acquisition, the initial data set is typically stored as what type of file?

• A. Encrypted image files
• B. Compressed image files
• C. Segmented image files
• D. Simple sequential flat files

Answer: (D)

When you acquire data in its raw form, the goal is an exact, unaltered copy of the original drive, including every bit, slack space, and metadata. To keep that copy simple and verifiable, it's stored as a single, simple sequential binary file—a flat file that records the entire byte stream in order without multiple containers or segmentation. This makes integrity checks straightforward: you can hash the whole file to prove it matches the original. Encrypted, compressed, or segmented formats introduce extra steps or complexity that can hinder access, verification, or analysis, so they aren’t the default for initial raw acquisition. In practice, raw images are often saved with extensions like .raw, .dd, or .img to reflect this unmodified, single-file form.
