![]() The primary purpose of an EnCase evidence file is to contain an exact bit-for-bit copy of the target media whereas Linux dd image, which contains only a bit-for-bit copy of the target media, the EnCase evidence file contains the bit-for-bit copy plus other information that serves to “bag and tag” the evidence file to preserve it for the chain of custody. This is often called an “image” file and is given the extension. The result of this process is a large file whose contents are a bit-by-bit copy of the original device. Alternatively, you could direct the copy to an actual file instead of a device”. “The copy produced can be a stream of data sent from the original drive to the copy drive, with the result being two identical drives, assuming the copy drive contained the same number of sectors. Using the dd command, you can copy one hard drive onto another hard drive with the apparent ease of copying a file, although the process certainly takes longer time. In Linux or Unix, everything is a file such as a hard drive, can be addressed as a file. The EnCase evidence file is also called as image file as it is carryover from the original imaging methods that had their roots in the Unix dd command. ![]()
