Well, if it's your interest to be sneaky and take other people's information, then the Forensic MD5 is just what you've been waiting for.

This is a hard drive duplicator designed for spies, law enforcement, and other devious types. I amost wanted one just for the spy-tech factor until I saw their website, which made me gag, which lables it as the "ULTIMATE WEAPON AGAINST CYBER-CRIME".

These spy devices are already being used by the police, FBI and auditors to duplicate hard drives in order to collect forensic evidence.

...The handheld has built-in USB connectivity and slot access to PCMCIA for laptops. It can also search for hundreds of words while capturing at full speed.
