Imagine CD-R media also Flaky, Fragile, Forgetful and Unreliable -- just
like what Mikey Richter (Lying Scum) said about CD-RW media.
Brendan R. Wehrung
Somewhere I have an article about the long-term durability of 78rpm discs,
which will last more or less forever, "like Grecian pots." And they're
direct-to-disc to boot. Who needs CDR when you can have that, Sammy?

You will note that the disc had many errors - presumably recoverable -
before aging. If a disc is poorly written, it is likely to be even worse
with age. In addition, this one clearly has inks which penetrate the
acrylic lacquer.
The point is valid: there are poor media.

Not much detail there, but I've certainly seen lots of CDs degrade
within 6 months or so. This includes TY, Kodak Gold, Kodak Silver,
etc. I also have cheap CDs (as well as the above brands) that have
lasted for years and are still going. Most of the older ones were
written at half speed on Plextor burners; full speed writing just lets
them decay even faster. Newer ones are on Teac and Lite-On burners;
I'm still testing them, but it looks like it's going to be the same
thing.
I don't care what the industry says about lifetimes, I know for a fact
this is a big problem.

Depends on how bad the failure is. Some of my older discs have areas
that are unreadable with any combination of hardware and software. If
you catch it early enough, you can make a copy. There's no visual
indication of trouble I've been able to find, even under a microscope.
For data:
The blue screen while reading is a dead giveaway. In less drastic
deterioration, my Ultraplex reader will slow down in the middle and
chunk away more, eventually reading it, but slowly. Generally a
burner will read discs that a reader won't, but as they get worse,
neither works, and you're just out of luck. Best bet is to try an
assortment of drives.
For audio:
I have several finicky readers, and some robust ones. My NAD changer
on the big stereo is the most finicky, and is a great test bed.
Generally, a music CD will work fine when freshly burned, but over
time, will start skipping and stuttering (burning at half the max
burner speed adds greatly to the life). The same CD works fine longer
in my Apex DVD/MP3 reader, but eventually will stop reading there as
well. I pulled out an old compilation from '97, and the NAD wouldn't
even play the first track without skipping. The Apex would read up to
about track 8 (of 15), but started skipping badly after that. The PC
had no luck reading the disc, but I didn't try EAC on it. I'll give
that a shot this weekend.
James Perrett
Decent media written in a good drive shouldn't be showing any errors -
at least in my experience of around 8 years of CD-R usage. If you are
getting any errors at all then you are either scrimping on the media or
have a faulty drive.
Plextor owners can use the CD Test function in Plextools to see whether
they have problems.
Cheers.

Nope, not a case of scrimping, even when media was really expensive
($5/disk and more). I used to use expensive drives until I figured
out that it didn't matter.
I've used various writers (JVC 2x, Plextor 4x and 8x, Teac/Liteon/
whatever in the 24x+ lineups) and the best media available at the
time, according to Usenet wisdom (not always based on fact, of
course), including Mitsui, KAO, Kodak Gold, Kodak Silver, and various
TY (as well as some cheap stuff here and there), some with labels,
some not.
Kodak Gold discs burned on a Plextor writer at half-max speed have
shown the problem of data deterioration.
Storage conditions vary for these discs, but even discs stored in
cool, dark, dry locations have problems, while other discs stored next
to them don't.
This is not something unique; lots of people out there have had these
problems. There was a long thread from Mac types back in 2000 here:
http://www.macintouch.com/cdrfailure.html
Lots of hypotheses, guesses, and tribal knowledge, very little hard
data, but plenty of CDR lifetime failures.
YMMV, of course, but CDRs are not archival by any stretch of the
imagination.
James Perrett
This is interesting because you list many of the same makes that I have
used. Maybe I should go back and check a few more of my older discs. Now
that I have a Plextor Premium drive it is much easier to obtain hard
error rate data.
Cheers.
James.

Sounds like a poor storage environment; Fungus needs H2O to propagate;
should there be any truth to this... Some legitimately documented
failures have been oxidation due to poor disc edge cleaning/lacquer
sealing which of course is a manufacturing defect.

I'd love to hear about your results, since there are a few variables
in my results I have little control over (where I live, for instance).
I'm just as interested in old burns that read perfectly as the ones
that have failures.
Unfortunately, I didn't start documenting the details until the last
few years, when the problem moved past the nuisance stage for me, so
the oldest data is kinda fuzzy. Maybe I should get another high-end
drive like the Plextor for the hard data...

This was a problem in the early days of CDs, particularly in humid
environments, but seems to be a thing of the past now. I don't know
how they fixed this; maybe better edge sealing... It's a good point,
as even pits in aluminum are no good if the substrate goes bad.
My first CD is still working quite well, and given the hundreds of
millions (billions?) of pressed CDs out there, you'd think we'd know
about any major problems. I bet they don't last as long as vinyl,
though.
I should have pointed out that gold was even better than aluminum, but
that's not going to happen on a large scale due to costs, particularly
in this time of (hopefully) decreasing CD prices. You used to be able
to get specialty CDs pressed with gold, for a few extra bucks. I
don't know if they still make these.

I did a few more tests last night and all showed no uncorrectable
errors.
The Kao discs from 1997 were reported as being manufactured by Ricoh and
gave an average BLER of around 0.3. The Kodak discs were slightly worse
with a BLER of 1.1 to 1.3. Even the cheap CMC unbranded disc from 4
years ago was only showing a BLER of 1.3. Some discs did show C2 errors
but this could have been due to them being recorded in track at once
mode rather than disc at once.
My first Taiyo Yuden disc was probably the worst performer with an
average BLER of around 5.
The early discs were recorded on a Philips CDD522 recorder while I'm
less certain about the newer discs as I would have had a Yamaha 4260 and
a Plextor 820 at the time.
Cheers.

While digging around on http://www.hydrogenaudio.org/ for MP3 threads,
I stumbled across this thread on dying CDRs:
http://forums.afterdawn.com/thread_view.cfm/3247
I also did some quick tests; not much time to dedicate, I'm afraid.
My most visible problem discs are audio, since I use them more than
old data discs and the problems are obvious. I dug out an old copy of
Johnny Cash - The Sun Sessions (burned about '98, most likely on a
SAF2006+ (oem JVC 2x), but it's hard to remember). It's in fine
physical shape, with no label and minimal Sharpie writing.
Here's what I found:
Disc: HP branded Mitsui, bought from CompUSA way back when.
ATIP: 97m 27s 55f
Disc Manufacturer: Mitsui Toatsu Chemicals, Inc.
Assumed Dye type: Phthalocyanine (Type 5)
Media type: CD-Recordable
Recording Speeds: min. unknown - max. unknown
nominal Capacity: 650.85MB (74m 05s 10f / LBA: 333235)
- NAD 515 changer (sensitive) - a few skips in every song, getting
worse on later tracks, unlistenable on the last few.
- Apex AD-1500 DVD/MP3 player - played all the way through fine.
EAC found no C2 errors using my Ultraplex PF-40TS.
Tried to extract the tracks using EAC, with these results:
- Plextor Ultraplex PF-40TS - 1st track dropped down to 0.1x
extraction, labored away for a while, and quit with the following
message:
Suspicious position 0:00:11
Missing samples
Peak level 0.0 %
Track quality 95.2 %
Copy finished
There were errors
The short wav file it managed to extract was full of blips and skips.
- Tried the same on my Teac 24x burner on this box, and it made even
less progress.
More tests to do, I suppose, and I need to dig my collection of
failing discs out of the archives.
dgk
I have cassettes and reels that are 30 years old and play fine. And I
have to worry about CDs that are three years old? Are we kidding?

This is a little odd - if EAC has problems extracting the audio then it
should also find C2 errors - in fact it should also find uncorrectable
errors.
Have you tried using the error checking tools in Nero's CDSpeed
(available separately from www.ahead.de)? You might also look into using
Plextools - if you don't already have a copy then do a Google Groups
search for Graham Mayor's postings about this software in this
newsgroup.
I've found that some older CD players don't like the pthalocyanine dye
that Mitsui use as much as other dyes, but this applies to freshly
burned discs as much as older discs. Silver Mitsui discs are also heat
sensitive - they have a lifetime of around 6 months if left almost
continuously in my office computer.
That forum thread you mention is interesting but there isn't really
enough reliable data there to draw good conclusions.
Cheers.

I thought so too, but it's very reproducible.

I'll give these a try when time allows; maybe this weekend. My copy
of Plextools is quite old (never had much use for it), but I can round
up an updated copy.

All my failing discs worked fine when freshly burned. This particular
one was in a stack of other unlabeled CDRs, in a dark corner. Some
heat there in summer, but nothing extraordinary. Part of the point of
this exercise is that Mitsuis were (and still are) considered
high-grade discs, and it's clear to me that they're not as good as I
hoped.

And that's one of the better collections of info so far!

Are these data or music (or both)? Do they have labels on them, or
writing on the disk? How were they stored? What speed were they
written at, and was it full speed on the burner? What brand of
burner?
My experience has been that errors on data disks are unnoticeable
until it can't read at all. That is, it corrects as the data slowly
gets weaker, with the only indication that the drive slows down (at
least on my Ultraplex).
Some drives are better than others at reading failing data (my burner
reads some data that my Ultraplex won't), which only delays the
problem, and doesn't mean that the disk isn't failing.
Audio disks are much more obvious, since the error correction is weak
and the skips are pretty hard to miss.
I have disks less than 2 years old that are failing badly (and some
that are still good), and disks over 5 years old that still read OK
(and some that are totally unreadable).
j...@friday.com
I like to make a .sfv file using quicksfv for the data on the cdr.
When I run the file after burning, it scrolls a list of files as it
check them. On bad CD's it will run noticeably slower, even pausing
at times. On good CD's it will go pretty fast depending on the file
sizes.
You can get a nice feel for what's going on with your CD. You can also
see specific files that may be problems when all the rest of the CD is
pretty good.
It's a nice little tool.
Jim Austin
Your posts confirm what I have suspected...all my recording on Fujifilm
CD-R that I made 3 or 4 years ago are no good. I realize now it isn't
my Nero software or the LTR-12101B drive... I've been in denial.
Is there any way to read the damm disks? Are there any brands or types
that will last longer than others?
