cd's failing after several months

[Subwars]

hey guys i've been having a bit of trouble with a fair few of my cd's.

after a while i'll get one of my movies out to go and watch it and the cd is just unreadable... won't copy the file, play it or anything.

i've done the scan disc thing with nero and it does come up with alot of errors but physicly the cd is in perfect condition i have them filled away so they don't get damaged... they just start to fail after some time there not exposed to any extream temperatures or anything so it can't be that and it's happened to about 3 different brands of cd's that i've bought

has anyone else had similar problems what could be causing it if there is a reason or is it just that the cd's are shit and work fine for a bit then from nowhere die which shouldn't be happening :(

:confused:

I have couple no-name CD which has errors and can't be read whole content. No scratch or other damage. But problems started more than one year after burning.
What to say? Buy other brand or buy brand instead no-name.

sometimes you can use a program called ISObuster to get most of the content out of the bad cd... you'll end up with a few broken frames most of the times and sometimes with a movie you'll have to reencode.

it's worked for me on no-name crap media several times!

Hello

Sorry to hear about your damaged CDs. I have been using Verbatim
80 Minutes Super Azo CD-R and Datalife Plus without problems so far,
some of them are reaching the two years mark.

I would advise that you make sure the CD was correctly burned before you store it, I have noticed sometimes that even when Nero reports the burning was successful, the cd is not readable, I check them a few minutes after writing to them for any kind of errors.

Yeah... buy quality CDR's, use verification when burning, and store the CD's dark, dry and cool.

Quality on CDR's was better before too I think...

I took the cheapest Fujifilm CDR, put it on my desk at work, and had a magazine put over half of it. After 1 month, the unprotected area had become all yellow... Sure, all CDR's breaks down from UV-radiation, since all plastics do (they're just more or less resistant), just thought there'd be better quality on some of them. The other consideration is that the writing film loosens from the plastic disc.

There was reference to a test at cdrmediaworld where they'd used Philips environmental testing machine, and during normal usage, the worst CDR's didn't even last 2 years...

I got CDR's here from -96 that works like a charm though, that has been just "laying around" without any protection at all. But I always store my important stuff in plastic sleeves, inside binders.

After a month sound very extreme though :eek: I'd look at the burner in that situation actually...

thanks for the idea of that program i might give it a try but i'll probably end up just getting the dvd again and doing another rip of it the movie should come out a bit better then as well with latest software available :)

didn't know that i'll do that in the future i just see that it comes back fine and then it gets stored thanks :cool:

i do try to buy the cheapest cd's i can get in big spindals so they wouldn't be the best of quality but you would still expect them to last more then they are... also my cd's do get stored in those conditions i have a type of filing box where the cd's are in sleves and inside an allmost sealed box so there pretty safe from any environment conditions

I'd look at the burner in that situation actually...

that could be a possibilty i'm pretty sure the cd's that have died where burnt with my old 4x burner i bought a new 40x one about 6 months ago so i'll just have to wait and see what happens

I just went back to my first CD-R ever ... burnt in February 1996. It is a plain ISO9660 disc ... unlabelled, the jewel case had a "Data master" inlay, and it is still working 100%. Quite a few scratches, actually ... I checked the ATIP and - what a surprise (NOT!) - it is a Mitsui disc :).

I also checked some barely-one-year old "Polaroid" cd-rs - none of them are readable using explorer, Isobuster can still extract some data, the silver has begun to oxidize etc.

Note that I don't want to advertise a particular brand here ... but I go for quality media these days (Kodak - no longer made, Tayo Yuden, Mitsui, perhaps Verbatim).

when you look at the specs of a cd with nero where it tells you the manufacturer and that, i was wondering if the dye types have anything to do with quality or just the colours and shit, are certain dye's better then others?

here's a good thread about that :
