Hi folks,
Just a quick question about your long term experiences with DVD-R discs.
I popped a disc I wrote about 6 months ago into my Lite-On DVD-ROM and tried to copy some files from it. Have way through an error popped up saying it could not read from the drive. I ejected and put the disc (completely unscratched and in perfect looking condition) into my Pioneer 105 and copied all the files to my hard drive without a problem.
Is this the signs of a disc that is about to croak, I havent had any other problems with discs in my Lite On before so am worried that either the LiteOn is about to bite the dust or that my DVD-R's are failing.
Any advice on this one?
Thanks,
Rikki

They use to say that cd-rs were good for 100 years. I don't think I'll be around to test that. Haven't read anything like that for dvd-rs but I think they are good for more than 6 months. I would look at the dvd-rom for a possible problem. Maybe try a lens cleaner disc for dvds to see if that helps.

It's more likely to be a disc problem than your Lite-On DVD drive. DVD/CD-RW burners are much more error-tolerant than CD/DVD-ROM drives. Had this problem with marginal media in the past.
If you have problems reading a disc in your DVD-Rom drive, i'd keep an eye on the disc as it is likely to be starting to fail. Cheap media has been reported to fail within 6 months or less (ie Princo's). The DVD-R discs i had to re-copy were Princo's...

Ran a program that identified the disc in question as being a PRINCO. It was branded as a Datarite 4x.
Are these notoriously crap discs?

Some people say they're cheap and shit and will only last 6-12 months as stated above, tho more than a few pioneer users on a forum i frequent say they've been usning princo disks since they bought they're 105 (i have a 106) and still play them in they're dvd players.
I think the problem is more likely to do with the renaming of grade b and lower disks, the princo A grade's work fine, but the rebadged B grade disks, (in your case a datashite) are shoddy, as with most b graded media.

oh, and merry xmas to all who are enjoying it, and if you're stuck with your family like me, drink a bit more, it'll be over soon enough.

What a can of worms I have opened for myself!
I have now copied the disc to another blank and checked my other media. I've also sent an email to Discrite (Medea) about the issues to see what their response is.

Hey guys,
just browsing round and I found this ABSOLUTE GEM of advice; the thread is entitled "how long do dvd-r media last?????" in the DVD-r for advanced Forum

they last forever, unless you scratch them, they dont detreriorate, thats one of the biggest advantages of digital video over analog. a VHS will degrade, a DVD (regardless what format) wont. All that happens is that they skip if they get scratched.
Looks like we got nothing to worry about!!
Have Fun...
Life is just more of the same:

I remember this article from last summer on cdfreaks:
http://www.cdfreaks.com/news/7751
A Dutch magazine tested the dye and some of the CDRs they tested had read errors after 20 months.
I got my first burner in 1994 and can still read the disks I made 9 years ago on Verbatim media.

drchips: Wasnt sure ;)
I started on the road to CDR heaven back in 1997. Firstly with a Delta IDE 2x unit then a Panasonic 4x SCSI and finally a Yamaha CDR400t SCSI. The Yam cost over £300 plus the extra SCSI card but was an absolute star for over 4 years. I still have really really cheap CDRs I burned back then that have chips out of the reflective layer and all kinds of scratches and they still read very well considering.
Suppose not having the industry fighting over two standards for CDRs helped there as everyone got behind the one idea and pushed it forward.

Guys,
CD-R and DVD-R work on the same basic principle, sure.
BUT, 4.7 Gig (DVD-R) in the SAME AREA as 0.7 Gig (CD-R approx) means that track density and/or sector density (in general, recording density) has to be much higher: agreed?
This necessitates a change of materials/technique/dye/laser optics etc. etc (remember, we are not talking about pressed disks here).
Just because there is a number of years experience with CD-R manufacturing, we cannot assume that will translate to the new medium with immediate success (an analogy: western motorcycle manufacturers vs. japanese).
One thing for certain though, it WILL get better, we are still in the infancy of this technology (think manufacturing NOT computing - different timescales).
Big name brands will almost always be of higher quality, last longer & be more reliable (and COST MORE).
Cheapo no-name, me-too margin cutting manufacturers are turning out product based on PRICE, NOT QUALITY.
So hang in there, buy the good stuff for the burns you want to keep & use the cheap stuff for give-aways & short-term use.
Have Fun...
