  • +1 for mentioning speed. If the disk is slow, take an image and work with it on something faster (i.e. SSD, etc.). Commented Jun 11, 2016 at 4:38
  • MD5 is considered broken by now, as in collisions can be generated on demand using reasonably cheap computers, and a competent opposing attorney might be able to convince a court it does not provide sufficient defence against tampering. I believe 256-bit SHA-2 is the current practical minimum for evidential-quality cryptographic hashes. SHA-1 collisions are still expensive to create, but a trial can take several years plus appeals, and computrons will only get cheaper. Commented Apr 3, 2018 at 17:59
