I don't understand why I am getting this error when I try to save the edit. The computer see the disk. I can play the program on the DVR, so why am I getting this message? I didn't have this problem before. I've edited almost 400 shows with no problem. A while back ReDo has a problem with what it said was a corrupted file. After that when I hooked up the drive to the computer to edit, I would get a message from windows the disk may need to be scan, but when I tell it to go ahead it would state it couldn't. That has been going on for a while but it didn't prevent me from editing ... until now. What is the problem?
