Why is it necessary to calculate hash values on the primary image made from a suspect’s hard drive? How many hash calculations do you make?
What will be an ideal response?
You calculate the hash value for the original volume and compare it to the value you get from the copy. They must match. If not, you need to figure out why it doesn’t and document the reason. How many do you make? That’s kind of a trick question. Ideally, you will make two calculations for each copy. If you have both MDA5 and a SHA-256 calculations for each copy, and each version matches, it will be very difficult for the opposition to challenge the validity of your copies.
