Actually it's completely true.
Waving a DVD through the air listening to what sound it makes would tell you absolutely nothing about burn quality and would thus be utterly pointless.
Doing any of the tests listed above, including a Read Transfer test, will not tell you everything about quality but they will tell you something. This is exactly what you are arguing yourself - except that you then conclude that the tests don't tell anything.
Please make up your mind! :bigsmile:
Yes, so it does tell you something - namely that the disc can actually be read, which in fact is the only capability of the disc that is absolutely ESSENTIAL. It does not however tell you whether the disc can be read in some other random drive.
Perhaps you're right, I haven't seen this myself. Even if it is the media itself and not the burn that makes it hard to read, I would consider that to be VERY relevant information - wouldn't you?
No, the TRT has failed to tell you everything about burn quality.
Are we having a disagreement over the meaning of the words "nothing", "something", "anything" and "everything" here?
In my experience the Read Transfer Test on one of my drives (NEC 3500) is the single best predictor of whether a disc can be read back in any of a handful drives, and PIE/PIF/POE/Jitter/Beta scanning is not nearly as good at predicting this.
Your experience is obviously different from mine, and it might even be more extensive, but don't be too quick in dismissing experience that differs from your own.
Yes, but they can also be essential for people who DO have a good scanning drive - provided that the Read Transfer test can be done on a drive that is a reliable predictor, as e.g. my NEC 3500 drive is.
No disc I have ever tested in my NEC drive that could be read at full speed (16x) have shown any problem in other drives. All discs that have been difficult or impossible to read in any drive have also shown this in a Read Transfer test on my NEC 3500 drive. Some of these discs do not show an excessive amount of PIE/PIF when scanned in my Plextor PX-712A drive, and I know from experience that my PX-712 specimen is not a particularly good reader (it shows roughly 50% to 200% higher PIE/PIF total on the same exact disc when compared to a friend's PX-712).
If I were to perform only a single test, given my selection of drives and their capability, it would be a Read Transfer test at maximum speed on my NEC 3500. All the Q-Scan tests on my Plextor PX-712A combined simply don't add up to being as good a predictor for reading problems in other drives!
