Actually, depending on the vehicle manufacturer, the EDR records only 5 seconds of pre-crash data (sometimes up to 20 seconds). What is recorded varies as well. Most common is vehicle wheel speed, percent throttle, brake activation, airbag deployment, seatbelt activation, velocity change, etc. It is a very useful tool to aid a crash investigator as well as an insurance investigator but again, it is just one of many tools and should not be used alone, but in conjunction with other investigative tools.
