Check your other post and CNET's Storage Forum's Lost and Found top post for freebies I've used.
This external hard drive data recovery was listed by CNET as "free." Upon use of the program I soon found the use limited to only 100mb of data recovery and therefore not "free" per your definition. I unwisely purchased the full program, which did not work (froze for at least 12 hours each time). I emailed their customer service three times with no response. Finally, I emailed for a refund. Again no response.
