Hello
I was ripping some CDs yesterday and found I had one that played very distorted on my new PC. (PC is new to me, it is actually a 2013 model)
The CD plays OK on another PC and on my hifi. My PC also plays all other audio CDs perfectly.
I have searched for new firmware but cant find any for that specific drive.
I have updated the PC bios .
I also changed the region for the drive to UK.
We moved the DVD player into Sams PC and the same happens there, the CD in question is very distorted.
Now I have Sams DVD drive the CD plays perfectly on my PC.
The CD in question is The Very Best of Fleetwood Mac and the DVD drive is a PLDS dvd+-rw dh-16acs.
So what is it that could cause this? It has me stumped.
thanks
Mike
What kind or model of cd/dvd drive were you using? Some of them , specially old ones require a thin extra cable dedicated to transmit music cds data
Hi
It was nothing like that, this drive was a PC Sata type. For some reason some drives dont work with copy protected CD's
Mike
Hi Mike.
The region code won't effect a CD, have you tried a second copy of the disc, could just be a faulty disc.
I have to say I did get the odd distorted copy some years ago but oddly only on Nero, never had any issues on Brassero on Linux.
Sorry the problem was not when copying as such, it just would not play with out severe distortion. It worked fine in another DVD drive and on a HiFi system.
The CD was bought in the UK but I cant say where the DVD drive came from as it was a second hand PC bought from Ebay. In the end my son said I could swap the drive with his one.
There was more discussion on the subject here; where we came to the conclusion that it was Sony/Warner copy protection/country code issues.

Hi.
If you have a minidisc recorder or DAT recorder try doing an optical recording, if the recorder won't copy the disc its got copy protection and is most likely the problem, if not it is possible there may be a small video embedded in SVCD mode that will cause problems with ripped play on a PC also but unlikely is the original is an HDCD.
One other thing to try is run your PC from a Linux live CD or stick and try playing the disc again or even rip it adain with Brassero I bet doing that will cure the problem.
All commercial CDs have the copyright flag asserted, but the generation flag is not. A digital recording (via TOSLINK or S/P-DIF) is permitted, but the destination media (MD, DAT, etc) will assert the generation flag (in addition to maintaining the copyright flag). This means that you cannot make a digital copy of the first copy. Which is a reasonable compromise, intended to allow the original owner to make a copy for car use, but not to allow distribution (although these are just a couple of bits in the channel-status data, so easily modified - which is sometimes necessary in professional scenarios).
My understanding of what Mike has is different, so won't be affected the above - his CD will behave normally in a CD player connected digitally to a MD recorder or similar.
That's because it appears to be a CD with a data session that is ignored by standard CD players, but is executed by autoplay on a Windows machine. This silently installs code on the PC that interferers with attempts to copy the CD. Sony got into a lot of trouble about that:

That is a really good reason to turn off autoplay on Windows machines. As far as I know, the code was only for Windows machines, so MacOS or Linus should have been OK. Certainly, with all those variables, it might explain why different behaviour was reported on different machines, although it doesn't explain why it was OK in Sam's DVD drive in Mike's PC - so perhaps it's something else entirely? Either way, this is a "zombie thread" from 7 months ago - Mike has resolved the issue.
Several years ago my son had a CD that he wanted to convert to MP3 but couldn't because there was some copy protection on the disc which prevented it being played on a PC. I had a look at the files on the disc and there was an extra file which appeared to be to do with the copy protection. Using Nero I extracted all the music files and converted them to WAV files which were then converted to MP3. Result one happy son.

Sorry to add yet another post to what Mark quite rightly says is a rather dead thread, but I am not yet convinced that the issue has been understood yet. The CD, when played in my PC with the original DVD drive was very distorted. It was not just an issue with ripping the CD it was both Play and Rip.
But anyway we got around it.
Mike
Hi Mike,
Yes, that is what the software does. The only mystery is how come it worked with Sam's DVD drive. But as I say, there could be another thing entirely.
As Keith suggests, it would be worth examining the CD using a tool like Nero to find out if there is a data session in addition to the audio.
I use
EAC (Exact Audio Copy) for ripping audio. When it is running, it takes full control of the drive, so preventing the OS from auto-running anything when you insert a CD (indeed, if you close EAC while the CD is still in place, at that point the Windows autorun dialog pops up). So, it's a really useful tool for ripping CDs without any hassles - I've no idea if I have any copy-protected CDs, but I ripped all of mine (over 500) using EAC with no issues.
