I like using dcfldd for creating the raw images, because it shows a nice status…it’s interesting to see progress.

dcfldd if=/dev/sda of=/mnt/sdb1/filename.dd hash=md5 md5log=hashfile.md5 conv=noerror,sync bs=4096

It’s the ‘bs’ (stands for bytesize) that makes the difference (…always does doesn’t it ;-).

Autopsy – The forensics browser always uses the ~/.autopsy as the base directory for storing the files from the cases. The following command is helpful in changing the directory in which the cases should be stored:

./autopsy -d /mountpoint/dirname

The exiftool is a cool application that can read meta-information to determine the different types of files.
