Raw data acquisition format creates _________ of a data set or suspect drive.

The correct answer is B. Simple sequential flat files. Raw format (also called dd format, after the Unix 'dd' command) creates a bit-for-bit, sector-by-sector copy of a drive stored as simple sequential flat files - meaning the output is a contiguous stream of raw binary data with no proprietary headers, metadata wrappers, or…

Explanation

Raw format (also called dd format, after the Unix 'dd' command) creates a bit-for-bit, sector-by-sector copy of a drive stored as simple sequential flat files - meaning the output is a contiguous stream of raw binary data with no proprietary headers, metadata wrappers, or compression. This simplicity makes raw images universally compatible with virtually all forensic tools. The trade-offs are that raw format does not natively support compression, encryption, or built-in error checking/hashing (unlike proprietary formats like E01/EnCase). Segmented image files and compressed image files are characteristics of proprietary forensic formats like E01 or AFF, not raw format.
