Explanation

Raw data acquisition format (also known as dd format, after the Unix 'dd' command) creates a bit-for-bit, byte-by-byte copy of the source media stored as simple sequential flat files. Every bit from the source is copied in order, with no compression, encryption, or proprietary headers added. The result is a linear binary image that can be analyzed with virtually any forensic tool. This simplicity and universal compatibility is its main advantage. Segmented files, compressed image files, and segmented image files are characteristics of other proprietary forensic formats like EnCase's E01 or FTK's AD1, which add metadata, compression, and integrity checksums.
