to my pc so i can back them up to dvd. I've contacted tech support several time with no help at all. They say only the software developers know anything technical about the file formats and such. I did a test recording and then tried to hook the drive to my pc and it didn't see anything on the drive. Seems like Windows changes the file stucture cause when hook it back up to my 622 it reformats it. I don't want to keep buying more and more drives when I can make back ups cheaply with dvd-r's. please help and sorry if this has been covered already i just found this site today.
