Getting evidence  by reading (via  any software or  hardware solution)
may compromise the integrity of the evidence. I would like to know the
difference between  for example a  (s)dd and the  specialised hardware
that you talk about ? Do you have any references ? 

Preserving  the  scene integrity  is  really  difficult.  You have  to
minimize the  intrusion to the  scene. On computer hardware  is really
difficult...  Using a hardware device that doesn't change too much the
scene is difficult... (think of a compromised disk firmware). 

And  the worst,  sometimes  we  see something  that  doesn't exist  at
all. Forensic analysis is the land of illusion... 

just my .02 EUR.
