I get this question now and again:  What are the differences between the Disk Jockey Pro IT and Pro IT Forensic?

The great folks at Diskology provided the following answer:

Here's the main difference between the PRO IT and PRO Forensic:  On the PRO Forensic (PF) the Drive1 side, or source, is ALWAYS write blocked.... there is no way whatsoever that anybody could ever accidentally erase the source drive.. So with the PF even if you have the unit set to erase, it will ONLY erase on the Destination, or Drive2, side... So the PF is completely write protected on the Source and it no longer has the Mirror or Span modes. It also has a 7-pass Department of Defense (DoD) erase instead of the 3-pass NSA (National Security Administration) erase.
