Melanie Was Newly Assigned to an Investigation and Asked to Make

Melanie was newly assigned to an investigation and asked to make a copy of all the evidence from the compromised system. Melanie did a DOS copy of all the files on the system. What would be the primary reason for you to recommend a disk imaging tool?

A) A disk imaging tool would check for CRC32s for internal self-checking and validation and have MD5 checksum
B) Evidence file format will contain case data entered by the examiner and encrypted at the beginning of the evidence file
C) A simple DOS copy will not include deleted files, file slack and other information
D) There is no case for an imaging tool as it will use a closed, proprietary format that if compared to the original will not match up sector for sector
