image, mount, calculate hashes: examples

I wish you all the best for 2010!

I’ve been working in an article related to serving search warrants and I thought the following examples may be useful. They cover imaging, mounting imaged drives and calculating hashes for every file in a drive.

CASE_ID identifies the case, LOCATION_ID identifies the location where the media was seized, MEDIA_ID identifies the media device and PARTITION_ID identifies each partition into the media.

This is an example for dcfldd imaging. The command calculates the MD5 hash on the fly.
See here for options’ reference.
