    Has anyone heard of 10 out of 50 memorex dvd-R 8x disks being bad at one time before, or do yous think it's my drive? Any feedback would be great.

    Only 10 coasters in a 50 spindle? That's very good for majority of memorex,lol

    Memorex? It's very hard figuring out which memorex discs are the good ones. Use nero/dvd decrypter/dvdinfopro/or dvdidentifier to find the actual mfg code. Post the results.

    More forgiving if you burn at slower speeds, but even if the burn was successful, it may not work after a year(or less).

    Damn, those are crap. As saugmon brought to my attention a while ago, stick with media made in japan.(Verbatim,Fuji,Sony etc.) If you do look into the brands I mentioned make sure they say made in japan because these are also made in taiwan.

    They should re-name this mfg ID code: CMC CRAP.AE1

    Quite a few posts on issues with this id #.

    Stick with japanese media. Fewer issues and better playability.Just look at the labels for Made In Japan.

    Once again I have to disagree I have burned a few hundred movies easily with maybe 3 or 4 coasters.Memorex is pretty impressive.

    Remember, the quality of a disc is [bold]not only[/bold] based on whether or not you get a coaster, but on how long the burn will last. Memorex is notorious for craping out down the line.(somtimes before a year) Also, not all memorex is cmc mag, but most manufactures that memorex puts their label on are not the greatest.

    They were on sale at staples for 19.99 for 50. Maybe they just got a crappy batch, cause these disks suck. I just ordered 100 of the Taiyo Yuden 8x, everyone on this site thinks there great. Thanks for everyones help.

    Hope you have better luck with those. You may want to burn at 4x just to be on the safe side.

    And movies27, hope your luck holds.

    What was the media code on those 5 year old Memorex dvd's and what speed were they back then?

    @ movies27 :



    Well i find that they have lasted longer than the five year span as research is starting to show that disc s actually dont last that long.Below is an add on to an article that scubapete did for me and the conclusions that are drawn show that the discs that are meant to last 100 years actually only last a fraction of the time

    Enjoy the read its really worth it.

    Eliminating errors and going for the "Best burn" ~ Tips ~

    When attempting to achieve the best burn, consider reducing that burn speed to the 4X area. Iffin you have a new 16X, DL burner, you'll probably do well at 6X. It is my feeling that 8X and over leads to occasional coasters, even when using top grade stuff such as Verbatim DataLife Plus media.

    The second part of the solution is to always use a decent grade media. I suggest something like those discs made by Taiyo Yuden, Ritek, Mitsubishi or RICOH. Unfortunately they are also the discs most plagued by pirate Mfgrs. and for that reason I like dealing with Mertline, Supermediastore OR Newegg who have a great return policy on their products. I have had great luck with RiData and Verbatim DataLife Plus discs and their prices are extremely reasonable. As a passing note, when buying Verbatim's, they come with a lifetime warrantee. Return them with your sales slip OR register receipt and a new one will be shipped to replace it.

    For the best online media stores to shop, try –

    In today's market, now more than any other time, beware of pirated fakes.

    DVD-R market plagued by fake media and inconsistent quality.
    Fake Taiyo Yuden media, and the current quality of RITEK products is discussed here. Is the quality of Verbatim affected by the fact that they are now outsourcing production to CMC, and Moser Bayer?

    The DVD recordable media market: What's up with RITEK?
    What a convenient timing - few days after we publish articles about the quality issues on the DVD recordable media market, RiDisc promises to start delivering premium quality. They use strong words in describing their new RiDisc Xtreme products - "Grade AAA+ RITEK G05" and "zero tolerance quality control".

    But then again, on another topic –



    long will your discs last ? You may not wish to read on . . . .

    FAIR WARNING. . . Using that "Cheap" quality media, your backups might not last all that long -

    One thing I haven't addressed is the life of a backup made on an "el cheapo" disc. We all know that data, music and video backups on CD's and DVD's will last forever, well, if not forever for at least 100 yrs or so - That's what we've read and I believed and that's why we backup our treasures to disc, so that they'll be safe. "BLAaaaT" (the bone chilling sound of an emergency air horn), Wrong, Dead Wrong ! Don't throw the originals away, you may very well need them. Your video camera tapes and family picture CD's and DVD's, may not be there the next time you want to look at them. "Point of fact," inferior discs have a tendency to "Break down]" in time. In a very short time, we're talking disc can breakdown in less than a single year, in as little as 6 to 8 months.

    This article was written about CD discs but DVD discs are exactly the same. I was miss-informed and this opened my eyes. Perhaps you'll find it as important as I did.


    Independent Portfolio Content



    Ever decreasing circlesYou know those CD-Rs and DVD-Rs that you've trusted your most precious memories to? They could be little more use than coasters after just two years. Michael Pollitt investigates21 April 2004 Are we putting too much faith in the ubiquitous "recordable CD", or CD-R? It is undeniably one of the most useful means of storage around, offering an inexpensive way to save digital photographs, music and files and costing less than 50 pence per disc.If you check the claims made by some manufacturers of popular CD-R brands, you will see that some make bold claims indeed. Typical boasts include: "100-years archival life", "guaranteed archival lifespan of more than 100 years" and "one million read cycles". One company even says data can be stored "swiftly and permanently", leaving you free to bequeath those backups of your letter to the electricity company to your great-great-grandchildren.But an investigation by a Dutch personal computer magazine, PC Active, has shown that some CD-Rs are unreadable in as little as two years, because the dyes in the CD's recording layer fade. These dyes replace the aluminum "pits" of a music CD or CD-Rom, and the laser uses that layer to distinguish 0s from 1s. When the CD is written, the writing laser "burns" the dye, which becomes dark, to represent a "1" while a "0" will be left blank so that if the dye fades, there's no difference; it's just a long string of nothing to the playback laser.So have you already lost those irreplaceable pictures you committed to the silver disc? PC Active suggests we should forget CD-Rs as a durable medium, after its own testing found some with unreadable data after just two years. "Though they looked fine from the outside, they turned out to be completely useless," wrote the technical editor Jeroen Horlings, who had tested 30 brands in 2001, left them in a dark cupboard for two years and then re-tested them in August 2003. Of the brands tested, 10 per cent showed ageing problems. And it wasn't just Horlings. After seeing the results, shocked readers contacted the magazine with their experiences.Recordable DVDs are not off the hook either. The "dye chemicals" in write-once DVDs are similar to CD-R, though recording density and disk construction differ. "We're in the process of testing DVDs and we're sure that the same problems will occur," said Horlings, who plans to publish his findings soon.Gordon Stevenson, the managing director of Vogon International - a company specializing in data recovery - is familiar with these shortcomings thanks to the experiences of his customers, one of whom commissioned Vogon to retrieve pictures of his second honeymoon from a failed six-month-old CD-R. "The dye layer was fading," Stevenson says, "but we were able to recover most of the disk. But these claims [of a 100-year archival life] are unhelpful and misleading. If you're spending 20p on something, you probably don't expect it to last 100 years," he says.In the wrong conditions, such as sunlight, humidity and upper surface damage, your CD-R will slowly turn into a coaster. "CD-Rs should never be left lying in sunlight as there's an element of light sensitivity, certainly in the poor quality media," says Stevenson. "I wouldn't rely on CD-Rs for long-term storage unless you're prepared to deal with them as recommended."Such views are echoed by the National Archives at Kew. "Generally speaking, we don't recommend CD-Rs for long-term storage," says Jeffrey Darlington, a project manager at the Archives' Digital Preservation Department. "We don't regard CD-Rs as an archival medium. Most of the CD-Rs on the market are not of archival quality." Instead of CD-Rs, therefore, the National Archives tend to use magnetic tape rated for a 30-year life. Also, they are careful to copy, check and re-copy to avoid losing information and this is also a useful strategy for CD-Rs. "If you keep doing that so the CD-R is never more than physically three to five years old, you'll be safe enough. A hundred years sounds pretty unlikely," says Darlington.Not all optical media is vulnerable. The rewritable variants (RW) use metallic materials that change the phase of the light, rather than light-sensitive dyes. Commercial magneto-optical and ultra-density optical systems are different too. Stewart Vane-Tempest, the optical product director at Plasmon, the archival specialists, has first-hand experience of unreadable CD-R media. "Some dyes are very robust, but others not," Vane-Tempest says. "The one thing they have in common is susceptibility to environmental conditions. I do a lot of digital photography and pay top price for media. If I have anything important, I generally make a couple of copies. I've not used CD-Rs for long-term archiving."Vane-Tempest also offers a tip. Blank CD-R disks have a code that your CD writer reads to find the best writing strategy. If this isn't in the CD-writer's inbuilt software (its "firmware"), the default may be a poor compromise. Vane-Tempest says that some "less scrupulous" Far East companies have been using other people's codes, with deficient results. However, there is a way around this which is to find out which brands suit your writer and ensure the firmware is up to date.While such matchmaking is useful, there's no way to assess CD-R longevity at home. All you can do is check periodically. As for whether manufacturers are guilty of using finger-in-the-air methods, Kevin Jefcoate, the marketing and product management director at Verbatim, says: "It's a bit more than guesswork because there's a lot of scientific evidence to back it up."The answer, Jefcoate says, is to use a climate chamber to accelerate the ageing of the organic dye. Using a relationship between chemical reaction rate and temperature, 100-year lifetimes may be argued for normal conditions. Jefcoate adds that he has never known users to complain of age-related failures? "We haven't had anyone complain that, after three to five years, it hasn't worked." It's easy to blame budget CD-Rs when things go wrong. Novatech's purchasing and product manager, Kriss Pomroy, suggests users buy a small quantity for testing first.The PC builder sells unbranded CD-Rs sourced from a Far East distributor that buys over-production from well-known factories. Are we saving pennies and taking risks? "No," says Pomroy, "You can get problematic batches, but that's as true with branded media." The company now sells two-and-a-half times more unbranded write-once DVDs than CD-Rs.The world's No 1 supplier of CD-Rs, Imation, talks of "saving precious digital photo memories" - exactly what many people think they're doing. Semar Majid, its technical marketing executive, hasn't heard of any ageing problems. "Optical media should last between 30 and 200 years," he says, "but it's dependent on storage conditions and how you handle it." He suggests transferring important photos to DVD, and keeping on moving to new formats.Another big maker, TDK, takes a cautious view with DVDs, claiming only a 70-year lifespan. "This does not mean that DVD is more fragile or unstable in time compared to CD-R; this is only because of the shorter experience that we have in manufacturing and testing this relatively young technology," says the TDK product manager Hartmut Kulessa. There have been no complaints about ageing failures.As the oldest CD-R is barely a teenager, there are no definitive answers either. But perhaps the last word belongs to Jeroen Horlings at PC Active. "We see a lot of manufacturers and they think that quantity is more important than quality," he says. "The problem will remain."For more info on CD-Rs and dyes: www.burnworld.com/cdr/primer/whatis.htm; www.xdr2.com/CDR-Info/Dye.htm



    My personal observations on this subject -

    I have had about 40 backups that have refused to play after being stored for a year or more. I test all of my backups when they are burnt to be very sure that there are no problems. "In the Golden, Olden times," before I knew any better, the Memorex, Maxell's and professional "Store Brand" discs (and any thing that was on sale) was what used before I switched to Ritek, RICOH and Verbatim (Mitsubishi Chemical Corp.).

    It is the poor quality stuff that I have been experiencing my trouble with. I noticed that backup DVD's I had, refused to play in my standalone player and on my PC. VOB files wouldn't play either and other discs that I backed up about the same time would "Freeze" part way through the movie. After switching to Verbatim and Ritek's, mostly the Ritek's because the price was right, I've not had 1 go "Flat" in over 1 ½ years. I still have some backups about 90 of them done on the "cheap stuff" and, as time wears on I lose a few more as I attempt to check them. I say to you, why did a backup play fine the end of "02"and "03" then "fail" in "04 ?? Some that were done in "03" never made it till "04" (it took me some time to learn, lol) Most of my backups from around March of "03" were done on the "good Stuff" and they still work fine today - not a single failure ! What about now ? Well, 2005 is the year, I'll wait no longer, before this year is through I'm going to test the rest and most likely re-record them onto a decent grade of media. It's been too long and I don't want to run the risk that I've lost an original OR one has been borrowed and never returned (like that's never happened, Huh ?). I want my discs back and 005 is the year -
    Don't go through what I did, protect your investment.

    As always, you have a choice -

    Whether you worry or not about codes, they are still on the disks that you use, and a simple Nero Info Tool check will let us know what those codes are. Or download a free DVDInfoPro http://www.dvdinfopro.com/ and that will even do one better with an easy code check and disk surface check.

    How about the speed rating of those Memorex disks that are 5 years old such as 4X, etc.?



    Excellent article andmerr! Thanks for that post!

    When I bought my Sony dvd burner at BestBuy, (being a novice) I grabbed a 50 spindle of Memorex DVD+R 8x. I figured it was a name brand, "Is it live, or is it Memorex?" and all - how could I go wrong? Well, I have burned about 10 of them (at 4x) and through DVD shrink, chose the "movie only" option so less compression. I haven't even watched them all the way through (only to about 10-15 minutes into to check them) - but most of them skip or stop a bit in places . After all I've read here, I am assuming it is probably just the crap DVD's I bought?

    I have 3 movies saved to my hard drive (ala ScubaPetes wonderful advice!)waiting until I get some decent media! Live and learn - this site has been a God-Send to me!

    I felt once, just once that Memorex was a decent media until I found some DVD-ROM drives and also some portable DVD Players and Laptops that could not play them. Then when I started to test media I burned only a year ago, I noticed error problems on the disks as well.

    Movies27 mentioned that he has had wonderful success with them, for nearly 5 years now, and I am trying to get Movies27 to let us know the Media codes on his burned disks, and also what speed DVD's there were back then. Maybe he will answer us soon with that information once and for all. :)
