DVD degradation

[uniks]

I don't have to tell you how frustrating it is when DVDs get CRC error without any apparent reason, then you can't install a game, copy the disc, etc. You have to do the acquisition all over again.

Can you tell me is there some source on the internet which tests DVDs from different companies and then recommends them?

Or at least can you name three companies that produce DVDs that don't degrade because of simple fact that time has passed. This optic technology is really starting to piss me off, you can't count on anything with it.

I am currently using Imation.

Here's what you need to do:

When you archive your files on DVD, use QuickPAR to create a parity set for your file sets.

Then, when you later try to get the files off the DVD, and you get your CRC error, you go get a program that will copy the contents of the disc, ignoring errors (I use IsoBuster). Once you get the files on the HDD, the files from the error sections will be corrupt. Use QuickPAR to rebuild and you're good.

Last week I was checking my older burns and the number of error in some of the disk has beginning increasing badly. Actually I was in the process of ripping and burning again some of my older recordings.

Imation is regular media. Lately I’m almost using verbatim media for all my projects. In average I get a quality scan of 95 and in some times better than that. I have tested plain +/- media, printable and laserscribe. No problems with a nay of them.

Over time all media will fail, but with a good burner and with good media, they will last for a long time.

this actually works?

I remember using all kinds of utilities including iso buster, absolutely nothing worked.

Here is what started me down this road. I had some older DVDs and CDs that when I tried to copy files to my HDD the Windows would just STOP. I use an Explorer replacement (Directory Opus) and I tried to find out if I could just ignore the bad sectors and keep copying. Turns out this is a Windows thing. Then I tried to Zip the whole disc, thinking I could zip the contents, bad sectors and all, and maybe end up with one or two bad files (this is totally different if part of a large exe gets broken). Anyway, Zipping did not work. Neither did Rar'ing.

IsoBuster does the job. It creates an ISO, ignoring the bad sectors on the disc, and then once on the HDD you extract the ISO contents. The beauty of PAR files is that even if a few PARs get damaged you can still use them to repair a fileset. So if you have 100 megs of files, and you create a 20% PAR set, you can totally lose 20% of the files and QuickPar will be able to fix it.

IT WORKS!
