Audio protection?

Hi I have a audio cd which plays fine in my Yamaha cd changer and also my plext premium using Audio cd player in Plexttools ,but when I run c1/c2 test there are tons of c1/c2/cu errors. This is the original pressed cd in perfect condition. Would this be a defective disc or some copy protection ?

Yes, it could be a copy protection.

How to recognize and copy/rip protected audio cds

Thanks for the reply but I’m starting to think it is a defective disc.
Ran it through clony -nothing. visual inspection -nothing. Nothing odd on the disc only 1 session and TOC ok. So I tried running the quality check of cd speed.
Premium goes through with 0 c2 errors
Lite on ltd 163 3 c2 errors
Plext 1610a finds 522 c2 errors (must be dying)
Lite on 52246s 0 c2 errors
All drives slow at the end though.
Also ran Kprobe with the 52246 .
@max speed lots of c2
@40 got 53 c2
@24 0 c2 errors
So if it is a protection it is pretty useless. (All my drives do a clean rip If slowed down)
Funny thing is I could swear I tried ripping it about a year ago with 1610a and ltd163 and could not get a clean rip.
Oh well no point trying to find problems that aren’t there anymore.

What CD is it?

Title, Label, Country, Batch number ???

i am not sure but on this forum or on the hydrogen one, is a thread where some “original” cd’s are scanned, and give bad results.

I will try to find it

@waspile

If your CD was really protected by implemented C2 errors, a lower reading speed wouldn’t help.

Disc damages or symptoms of old age don’t have to be visible.
Also, the BLER of CDs tends to be higher outwardly (thus drive slowdowns may occur).

Just in addition to the above said, why don’t you download and test your CD with an utility like e.g.
ClonyXXL to determine if there’s a potential protection or not ?

Sorry took me a while to respond here.
The cd is Faith No More -Who Cares Alot? Greatest Hits disk 1 is the one that causes problems. Bought in Canada. Slash Records, I’m not sure what you mean by batch, would W2 47149 be batch#? original release date 1998 but I bought it early 2002.

I actually did run Clony XXL on it and it doesn’t detect anything.

The first time I tried ripping this disk it was brand new out of shrink wrap so I have trouble believing it is deterioration but I suppose it could have been in storage for awhile before.

When I run Plextools c1/c2 with the premium @8x it shows no errors, only @10-24 ,but a ton near the end starting around 95%, even CU. Just seems odd to be getting so many errors at such a reasonable speed. If I scanned a disc I burned like that it would be in the garbage!

I guess it just doesn’t like my plextors.

I checked the known currupt audio cds database and that one didn’t turn up.

Have you tried ripping it on another drive? I know my Plextor 40x is very sensitive to audio errors. I had some xmas cds I made a few years ago (that had errors) on them and Plex wouldn’t rip it!

My other drive did w/o any errors too!

So you can give that a try.

FYI Batch number is written in the inner circle on the CD-ROM it’s self.

It doesn’t make sense that a pressed CD would have errors unless you have phyiscal errors on it OR it is actually defective.

Is that a PX-40TSi you’re talking about ? If it is I’m very surprised. I own 2 of those (FW 1.05) and I consider them to be very strong audio rippers. They even beat my premium when it comes to scratced cd’s.

@waspile
It sounds like a defective cd, as Audiocopy also mention, but you could try Swiss scout easyscan , it somtimes find somthing that clony dosen’t

It’s the PX-W4021A IDE drive.

I’m not sure what the firmware is or how I can check?

This one can be very picky believe it or not.

Well, we are talking about two diffrent drives. Mine are
a CD-rom drives and your drive is a burner. Sure I belive you
when you’re telling me (and ohters) that your drive is
sensitive to audio errors. But it’s quite unusual for plexie’s.
At least to my knowledge.

About the Firmware:
If you got plextools installed just
select your drive and then hit the ‘drive information’ tab.
Nero, Clonecd and ohter software can also show you about the
firmware revision.

I guess you’ve made a little typo about the drive name, but perhaps you should check for a firmware upgrade here.

No I got it used and plextools didn’t come with it, so I never used it. Any idea where I could download them?

That’s the name on the windows info, don’t think there was a typo.

RW drives can be more sensitive for whatever reason, I find ROM drives better at reading.

You can download Plextools Pro from this link.
But since you don’t has the original software,
you’ll have to aply a regfile before you install it. It’s described in
this thread.

About the typo. I did google the name of your drive, but I
only got one hit, I also searched on plextors site, but diden’t
find a match. Thats why i belived it was a typo.

Thanks a lot, got the plextools :slight_smile:

Well it says:

40/12/40A

PX-W4012A

I see the 40/12/40A listed but not that number and it isn’t a typo.

Even the cloneCD read is:

So got me? I guess that update will work? Firmware is 1.05
