I always tell Nero to verify if I have the time. The NEC 3500 can verify an entire disc in about 5:00, so the loss in time is minimal. I don't copy the files back to my hard drive as I feel this step is generally unnecessary.
Previous versions of Nero had some problems and bad data would verify OK, particularly on disc to disc copies. The very latest version seems to fix that problem, so I feel that the verify mechanism is now reliable.
If you want to be absolutely certain that your copied data is OK, you can use a Windows routine to do a file compare as follows:
- Click Start->Run to get the "Run" dialog box up. On the input line type the following:
fc /b "filename1" "filename2"
Replace filename1 and filename2 with the full pathname of your two files. For example, let's say your DVD burner is on drive D: and you've just copied the movie "The Aviator.avi" into it. Let's say the movie was located on drive "c:" in folder "movies". Your command line would look like this:
fc /b "c:\movies\The Aviator.avi" "d:\The Aviator.avi"
The two files would be compared and any differences would be highlighted.
