In my further ripping adventures, I ran across another CD-R that has no visible scratches, yet refuses to rip or play:

Robert Scott Thompson - Blue Day

It appears to have a paper label on it.  The plastic has turned a bright yellow color.

The CD-R problems totally outnumber the CDA problems so far (5:1 or so)

I've emailed Aucourant about a replacement.

Dang.

Two clinkers in one day.

The latest is a previously unopened CDDA:

Amir Baghiri - Ghazal

The 2 last tracks have multiple errors.

Jim
what exactly do you mean by 'multiple errors" ?
and does that mean the tracks don't play ?

I use dBpoweramp to rip.  It uses the Accuraterip database and C1 error reporting from the CD/DVD-ROM among other things to produce a precise copy of the music files.

If it hits unreadable errors, it reports them as frame errors and it rereads them repeatedly at reduced speed until the data is obtained or not.

The Baghiri disc (brand new, never played) had like 700 errors in the last track with no visible scratches.  It slowed down more and more to read the errors but never could.  I canceled the rip.

The Robert Scott Thompson disc was unplayable and unrippable.

I placed the Baghiri disc in my crappy home stereo CD player, and it seemed fine.

My "beef": I am unable to archive and stream these unrippable songs through my new system that is designed to replace CDs.

It may be debatable if that is a legitimate problem or not, but CDs may be going the way of vinyl because of their susceptibility to damage/poor manufacturing and because it is much "handier" to be able to dial up whatever music than to physically get a CD, put it in the player, and change it out at the end.

Squeezebox (my music server) has allowed me to rediscover so much of my music because basically it's playing all the time now...without having to change CDs or change out a CD changer.

I now have 37,000+ songs in .flac format on the hard drive of my music server.

Squeezebox is actually a family of players which are linked by Wi-Fi to the server computer.

There is a high end receiver (Transporter) and low-end (Boom).

I have one Duet and one Boom, and I plan on more.

Do you have access to another CD/DVD-ROM that can rip your discs? I'm wondering if you current DVDrom is the problem and not the discs themselves, especially if they play fine in your regular CD player. If the laser is going bad you would probably get lots of errors, using a different DVDrom device to rip with would probably eliminate one or the other.
Take care.

Thanks for your reply. 

I am using a brand new computer with 2 drives.  Both get the same errors.  And it's not on all discs.  I'm getting the errors on probably 5-10% at most.  In many cases the software will correct the problem by reading and rereading until it acquires the "data"; however, in some cases, the data just is not there anymore.

I suspect the CD player does okay by interpolating.  I have very cheap hi-fi equipment.

However, as I mentioned, a couple of discs are totally unplayable even on the CD player: the Matthew J Harris "Blind Cinema" and the Robert Scott Thompson - "Blue Day" discs.  Both are CD-Rs with clear deterioration.

Unfortunately as I rip my large collection of CD-Rs by Mathias Grassow, I am getting quite a few errors.  Dang again.

Hi,

I have had a few problems with CD-R's too. When Lloyd Barde was known as Backroads Music, he replaced a couple of Oophoi CD-R's that went bad for free. When James Johnson was involved in Atmoworks, he replaced, for free, a couple of CD-R's I had got from him.

I seem to remember the Oophoi discs I had did have a paper label on them. For the disc to become unbalanced in the player might be a possibility, but I'm not having issues now.

I can't guess what the problem was with James' discs.

Life is strange.

  I have been checking some of the CD-R titles in my collection that have been mentioned in this thread and have been lucky so far but still have many more to check. Unfortunately my copy of "Lumina" by Vir Unis is toast. Too bad! 
  The last time I was in California during the late summer of 2007 I talked with Lloyd Barde and he made it pretty clear that he didn't really care for CD-R releases. Probably because of the return and replacement hassles. I think I will check the Saul Stokes wooden box releases now. It would a real shame to lose those!
Peace, Kirk

The latest title with fairly extensive errors is a CDDA title which was new: Robert Rich - Calling Down the Sky.  As on most CDs, the error-prone tracks are the last two.

It had about 130 errors on it.  As it take 5-30 secs for each to be re-read, it will be sometime before I find out if the error-correction process was successful.

I'm sure it will play fine in a CD player.

Several of Mathias Grassow's CD-Rs were so error-prone on the last track or two, I had to use an alternative ripper that apparently ignores errors and just plows through.  While those rips will not reflect what Mr. Grassow intended exactly, at least they can be accomplished.

The reason I am finding so many of these errors is that I am systematically going through my entire collection which consists of approximately 15,000 CDs.  The overall problem rate is actually fairly low.

As I am ripping the tracks to .flac, I am also converting the files to .mp3 for use on my stream at http://zzzone.net.

So I ran into a CD-R with a paper label that had turned yellow and the disc was unplayable and unrippable.

I probably purchased the disc 6-8 years ago.  I do not have a receipt.

I approached the CD label about replacing the disc...a direct swap even - bad disc for good disc.

The label stated that they their policy was to NOT replace any discs except those that were purchased directly from the label.  They stated that I should seek replacement from the vendor from whom I purchased the disc; that vendor could purchase a replacement from the label at cost.  The implication being that I would pay AGAIN for the privilege of having the CD.

This comes despite the fact that I link in three places to the label on my site, and I legally stream the label's music (royalties are paid) which hopefully promotes the label.  Also I have no ads on my site to make money off the label's music.

Geez Louise!  What kind of malarkey is this?

How much can it cost to send me a replacement disc in exchange for a defective disc?  How do I exchange the disc with the third-party vendor when I obviously do not have a receipt from 6-8 years ago?

Talk about customer and fan UN-friendly!

I just needed to vent.

The latest problem child is a conventional CD:

Blood Box - The Iron Dream

The last track (as usual) had nearly 3000 errors that prevented ripping it.

This CD was brand new and in cellophane.

To reiterate the problem: when tracks appear like this, I cannot rip them to the exact equivalent lossless state for future listening.   

Reason: for whatever reason, the disc does not contain the original music information.

Jim,

In some cases, would it be feasible for you to pop the CD-R or CD into your CD Player, transfer the tracks to a cassette, and then transfer the tracks again into your computer system? I have heard that there are USB enabled cassette decks out there, just a couple of brands are available (sorry I can't remember which).

It's an extra step, but you might be able to get more information for your file conversions, and maybe get a bit more out of your music investment.

Anther CD-R with a paper label with many problems, brand new out of the wrapper:

Matthew J Harris - The Cure May Never Come

http://www.discogs.com/Matthew-J-Harris-The-Cure-May-Never-Come/release/1555332

It has 99 short tracks, all untitled.  It's dated 2002.

The last 50 tracks or so have multiple errors each, many of which are not correctable.

What a shame about these new discs.

I heard from Mr. Harris, likely as a result of this thread.  His Blind Cinema disc is set for a re-release.

you can buy a kit that transfers directly from the back of any steroe amp or cassette deck to a usb port. it includes software to enhance the transfer.

I appreciate the help but all I want is the original music on the disc.  A brand new computer and two brand new drives cannot read the data so it's likely just not there.

I'm not sure how a cassette arrangement or converting to analog and back to digital will give me the original .wav with which the CD was created. 

That's what I purchased and that's what I want to archive.

Call me stubborn and/or hard-headed.

Thanks again.

I mentioned this awhile ago in another thread--I have had some success saving the music from scratched or damaged discs by using a dual tray CDR recorder to make a clean CDR copy (at 4X) onto an audio CDR blank.  I don't know the specifics as to why it works, but it may be that the CDR recorder somehow reads the data differently than a conventional CD-Rom drive.  The copy also preserves the indexing between tracks, which is nice.  I have rescued a number of scratched and seemingly unplayable discs this way.

This is one of my most frequent activities lately:

http://zzzone.net/photo/2009/dbpowerampripping.jpg

I need to get out more.

Only a small percentage of discs don't rip.
