Re: Can No Longer Read CD's

Considering that the drive worked fine with a few dozen other discs (mainly Sony), I'm putting the blame on the Maxell discs. The drive deteriorated very quickly once I started using them.

Cheap DVDs from spindles tend to not last very long, especially if they are stored somewhere to can get very warm (doesn't have to be warm for very long).

Also, did you even bother checking if they worked after burning them? You may have burned a complete set of failures.

I have CD and DVD disks i burnt back in 2003 and they are still good today (but not really using them anymore). I have always bought the cheaper disks. I have used many maxell from walmart (but i check the Media Code if it is not good i take it back). The main thing is to make sure you buy disk that are known to work good with your drive model. I would buy a drive based on what media it was compatible with using this site to look up the details from customer comments. You can look up both Writers or Media.

Some DVD burners will not work good with some Media.

I had one case of Maxell disks from walmart that was opened when i buoght them, it turned out it was a bad batch of disks, I used about 20 without error (i think they replaced the missing ones from the last person that returned them) then the next ten would not burn a good disk (the Media code was a cheap version, known bad). I took them back and got a full refund even with 20 disks missing.

Re: Can No Longer Read DVD/CD's

Thanks for all the suggestions/responses.

I have come to the conclusion it is bad media. I tried many of them on 5 different players now.

A program claims the DVD's and CD's are RAW type files on them.
Not sure how that happened. They were anything but that type of file.

The majority of them were Maxell type media, so I will never buy them again!

I also noticed the bad ones were thinner than the other DVD's I have which still are working after the same amt. of time.

I sure have a change of mind when it comes to DVD's and CD's now.
I don't see why they don't last forever if a good burner is used.
I guess this technology has quite a ways to go. Makes me wonder why even bother if they claim not to last more then 8 to 10 years anyway.
I have cassette tapes (personal music recordings), from back in the 70's that still play and sound good.

Live and learn....

Unfortunately, with various qualities of organic dyes and adhesives used in recordable disc manufacturing, it can be hit or miss with long-term reliability. I've thought about picking up a burner with this technology and giving it a shot. Looks interesting at least.

Various postings are surfacing across the internet from professionals and hobbyists alike, reporting that over time permanent ink has made their properly stored discs unusable. There is no apparent reason for the corruption other than the ink used to label the disc.

Many people use markers to write on the surface of their CDs and DVDs when labeling their media. What most people do not know is that using markers, such as Sharpies, ballpoint pens, or any other sharp object can be very damaging to the media.
Most markers contain chemicals that create
oxidation, which can deteriorate the CD or DVD. The oxidation can ruin the aluminum, which covers the surface of the media and ultimately can destroy the data on the disc.

Re: Can No Longer Read CD's

Maybe it is a different process.

It is. Professional recordings outlast consumer recordings because of how the data is written to the disc. The professional ones use bumps & grooves to send the data digitally while CD-R's (consumer discs) use a special layer which the cd burner makes darker. This mimics the effects of the bumps on a professional disc.

The special layer is far easier to ruin than the bumps are.

Interesting read. Wouldn't you know it, I did use Sharpies to label them.

Well....live and learn...damn

(thanks for posting this)

It's worthwhile to note that scratching the *top* of the disc is actually far more likely to render a disc unreadable/unusable than scratching the bottom is.

The same idea applies to the markers. Light scribe has fared better so far since it utilizes a special layer independently of the burn layer which is, of course, isolated. Light scribe hasn't been around long enough to stand the test of time but a consumer CD that still works after 10 years is really pushing it in my opinion.

Bottom line - no media should be a sole backup solution. Ever.
