When recovering data, the process of copying all information between a header and a valid end of file marker is known as what?

The process of copying all information between a header and a valid end of file marker is known as data carving. This method involves searching for files or structures in unallocated space or data fragments on a storage medium, allowing the recovery of files without relying on the file system's metadata.

When executing data carving, investigators look for specific patterns, like file headers (which indicate the beginning of a file) and end-of-file markers, to identify and reconstruct files. This is especially useful in cases where files have been deleted or the file system is damaged, as it bypasses the filesystem structure to directly recover data based on recognizable format signatures.

Data slicing, file imaging, and file approximation are not the accepted descriptive processes for this method. Data slicing typically refers to breaking data into smaller segments for processing, file imaging involves creating a bit-for-bit copy of an entire storage device, and file approximation relates to estimating the contents or structure of a file without complete data. Thus, data carving is the most accurate term for the specified process of recovering data between a header and an end-of-file marker.
