worst scans that still play

[mc4man]

I'm a firm believer in the value of scanning to check media at hand to match to my individual burners and to find the best burn speed ect. I also think that dye fading is real and one should try for the best possible burn for long life
On the other hand....
(note) these 2 disks are (were) in pristine shape, no dust, lint, stored properly and currently in the garbage, but they do (did) play fine on my dvd player

[NightTran]

I had the same thought myself, would you date it then play again and again util you can play it? just want to see how long after that you can't play

Thanks

[mc4man]

if your serious I'll grab it back out of the trash can (one is long gone)
As a test I burned 2 consecutive this july, the best one is being stored
dark, cool, ect. and never played. The other one is being stored in keepcase
in living room, alittle sunlight, hot, cool, ect. and being played every once and a while (i love the 1st 20 min.) I thought I'd rescan every 6 months and see

The 3rd scan is from the same timeframe as the ones from previous post on better media and has held up

ALI seems to be getting better with time

how wouldd you explain a disc that Nero Speed will not scan, but yet it plays back fine in my Pioneer Home Theatre?
I know it is not the best quality scan, but I wanted to get an idea what it would score, but Nero Speed will not read it.

I checked some discs I burned in 2003, 2004, Verbatim and Plextor (TY) and Maxell (TY). Bought at 4 dollars each at that time.
The results from cddvdspeed are disappointing. But most seem to play fine in a standalone dvd player. Some Verbatims 4x cannot be read by my new NEC3550 (they have read errors near the end with dvd decrypter) but my Vaio drive can read them without read errors.
And of course these are the best discs at that time. Some other brands go directly to the trashbin.

CDspeed quality scan is excellent for differentiating better burns, a comparison of disk transfer tests at different speeds in different drives is more useful for determining playability in standalones and readabilty in computers. Recovering data and reburning low quality dvd's is a prudent action even if they still play. Standalone players are designed for a different purpose than dvd drives and reading at 1x the better ones will almost always be able to play disks long after they cease to be readable in a computer dvd drive. Locking a program like cdspeed disk transfer or dvdd at a low speed can simulate or imitate standalones, but even then recent tests have shown
newer generation computer drives are not being designed to read slow.

Does your DVD burner scan other dvd burns? (Some burners won't work with the QS scan, like my LG)

I have been testing a lot of my old burns too and finding simalar results that still do play I have actually used some of them re riped as .ISO and re burned some on new better DVD's and now get a high score.



Amazing thing is you think you have a good burn cuz it plays well but then you test it and find out its crap.

[Dan]

I do the same thing PA. I think part of it is peace of mind. Knowing you have a good quality movie on reliable media. Once I saw my first bad QS, there is no way I would keep it and say oh well that will do,lol.

So Chewy, you are saying that to check a backup if it`s ok , we should do a transfer rate test (with cddvdspeed) instead of the disc quality test?
And are there some limits in this test to decide to replace a backup?
At max speed if the transfer rate curve is normal we should keep the disk even if it has a low score in quality scan?
To replace all backup disks every 2 or 3 years is very expensive in time and money.
If the backup is barely readable, we should make another from the original all over from the start or just copying the backup it`s the same thing concerning data quality?

[Chewy]

I spot checked my problem disks after 1 or 2 had playability problems(usually on iffy players), I quickly found out certain types like memorex and ritekG05's
almost all scored 0-50. Using this method reccomended by a mod over at cdfreaks I found which mids were the worst(after almost 3 years I had a lot)

some titles I didn't care about, some I wanted on the best media I could find

many of the originals were used disks I got from rental stores or even pawn shops, many backups were made with old pioneer dvd burners that would read anything(30 minute rips). Most all play good but won't read in my fast nec's with riplocked removed. My LG saved me with reading the worst originals and backups. Rather than worry about transfer tests I would just
use shrink to try and read to the hard drive, if the nec's wouldn't I would use the LG.

If your originals are pristine and put away for safe keeping, don't worry, some of my series disks I would hate to recompress tho. I probably pitched several disks I didn't need to, but with TYG02's so cheap I wanted better backups.

Hi folks,

@mc4man, did you happen to run a "ScanDisc" test using NERO CD-DVD Speed program? If so, did you see a lot of "Bad Sectors"!
My experience is in that case the dvd might play back (iffy) but you will NOT be able to copy it (re-rip) onto a new dvd blank.

Q: A question for all of you folks ... if our dvd back-ups are degrading after couple or few years and not playable ... would it then be better if you back-up your originals to Hard Drive ... and to get more on your HD ... may be convert from DVD to AVI and then archive ... and it can be played back on a Phillips DVD Player ... which now comes a USB connector in the front of it?

Thanks,

G!

now look at the quality scan
would you trust that disk for another 3 years
I didn't and reburned it long ago

I saved the old burn to loan to the kids
