I have two NEC DVD+-RW NE-3450A drives. I suspect they are getting worn out (or just getting dirty?) since recently they started producing more and more coasters, on different brands of media. Before I invest on more expensive media or get a new burner, how can I test the drives? I read a lot of threads here, especially the test with Nero CD-DVD Speed. But I still have at least two basic questions.
What kind of media should I use to perform the test? It seems without inserting a CD/DVD (either blank or with data), I cannot do a test.
How can I tell if the drive is bad (or less functional) once the result is out? compared to what standard? say, the test reports an averaged writing speed of 3.8X, ... it seems slow, but how do I know it is because of the media or the burner?
