RiTEK is unpredictable in quality. As with all media types out there, there are good batches, and there are bad batches. But with RiTEK, there seems to be a lot of bad batches. :rolleyes: How does your drive burn on other, more decent media? If it looks just as bad, then it's your drive at fault. Otherwise, then you got a bad RITEKR03 batch.
Edit: Okay, I just noticed after answering this that you had started a thread about this, in which you provided more information than you did not here (information that knda makes my response irrelevant). In the future, do not crosspost! One post is enough. Posting about the same problem more than once is against the forum rules.
