I burned a dvd-r on an aging drive today. When I first got it, I burned 10 discs with it, then I got a dvd decrypter error while burning so I didnt trust it anymore. It Has Copied COUNTLESS discs since then. Probably in the neighborhood of 1000 discs. I guess my question is this. Does vibration cause the result that im seeing here? An equally aged burner yields the same results. Good at the start, Errors peaking toward the end. Oh.. and why cant they make a more solid construction to prevent the disc vibrating. E.G, miniature rollers on 3-6 sides of the disc? My 820 has even worse scans. It wont be used anymore!
omegaman7 You might have better luck if posted in this one..Those guy's are scan happy!! LOL http://forums.afterdawn.com/thread_view.cfm/54/540688
born2ride is correct is saying where you will receive the most help. However, in my opinion this is a very good scan and nothing to complain about. You only had a few spikes above 1 on your PIFs and your avg. was 0.0. Your max was only 54 on your PIEs. IMHO, a pretty darn good burn.
There is nothing wrong with that burn at all. Here is an excellent thread to help you understand what you are seeing: http://club.cdfreaks.com/f76/interpreting-pi-po-error-scans-80545/
Actually, Thats well below my usual average. Its the outer area of the disc that concerns me. Especially on my Dru820. It has an obvious problem brewing. This scan shows this drive to be starting the same problem. I will however agree that this disc/scan is nothing to throw in the trash by any means! Afterdawn wont allow this image to show, but if you want to see it, this is from my DRU820. As you'll probably agree, this drive is beyond its usefullness!!! http://img356.imageshack.us/my.php?image=2ndtyg02bg6.jpg
indeed. Here's the only time quality scanning proved useful, and even then it wasn't really that useful as it couldn't be re-backed up anyways.. - from http://forums.afterdawn.com/thread_view.cfm/193298 My comments re quality scanning - http://forums.afterdawn.com/thread_jump.cfm/715958/4353254
Scan doesn't look all that bad, remember though the acid test is how well it plays in your DVD player. In my humble opinion, my respected colleague Cincy Rob spends too much time hashing over the raw number scores on these. As long as they play well in your standalone device, you are fine. I've had one drive die on me, and it did not give any prior warnings that the quality was deteriorating, just stopped burning one day. I hope this helps.
Thought I'd toss in my I think what you are seeing could be wear in the lens movement assembly of the burner drive combined with potential increased tracking error at the edge of the disc. Also remember that this scan is of how this drive reads this disc.
Reads?, this disc? I always use the lite-on to read. People say that their excellent readers. My lite-on does nothing but burning and reading. My Dru840 does 80% of the burning while my lite-on watches the others like hawks. LOL. My lite-on has informed me of MUCH.
WOW creaky! Thats horrible. Ive seen a similar scan with a datawrite. Worst disc ive ever seen. I wouldnt trust those discs as coffee coasters, LOL. I really wish the industry would try harder. There just isnt any pride anymore. Its all about the money and production numbers. THANK GOD for TYG02
Scans are graphic displays of error correction activity. The errors are a combination of disc and drive errors. The upper lift seen in the first scan is common with discs for mechanical reasons that could be related to the drive's stability and/or to the uniformity of the spin-coating at the outer edge of the disc. Scanning at 1X is the most accurate measure for the combination of the drive and medium in question. BliveNC has a point about not worrying about raw scores--they'll change for the same disc at different scanning speeds, in different drives, and with different scanning software. But you may not be "fine as long as they play well in your standalone device" because they may be very close to the threshold past which the disc may not play at all. Scanning is a way to see how close to the threshold you may be. A disc with a score of 70 will probably not look any different from a disc with a score of 98, but the 70 will bite the dust sooner.
I can agree with that. I dont know much about this stuff. But I dont take coincidences lightly. 4X is what I always scan at. Scanning at different speeds opens up a NEW VARIABLE. I try to keep my testing to few variables. So that when I see a flaw, I can trouble shoot it easier. My 820 scan is IN MY FACE. And every burn on the 820, and read by the lite-on yields the same/similar result. I knew with the first scan of the 820 that it was going. Coincidences/Spontaneous...FEW AND FAR BETWEEN.
