After several unsuccessful attempts to get an answer from Panasonic, I thought I would try to find a solution here. I have a Panasonic DMR-E85HP. The mother board is shot and needs to be replaced, which I am unhappy about but I am willing to to deal with it. Problem is this...If the service center replaces the mother board, they will have to reformat the hard drive and I will lose everything on it. Cannot happen. I HAVE to retrieve the video from the hard drive. I have since removed the hard drive from the unit and want to know if I replace the 120G hard drive with a brand new one, have the mother board replaced, can I than swap out the new hard drive with my old hard drive and simply view the vids as I was able to before????
