c2 problems

I actually do the same and have the same system as you have. Even with perfectly newly bought cd's, straight out of the plastic, the C2 always kicks in and takes forever. I eventually always have to force quit the program and turn of C2 so I can actually rip the disc.
However, I always very much doubted this would be coming from a hardware related issue, I always thought I probably missed a setting or something (although I did try everything I could think of). Don't know what it could be though ...

This may be a hardware issue- I have essentially the same laptop (MacBook Pro 2.6GHz) with essentially the same drive (UJ-867) and have no issues with C2 support. I'm not sure what the differences are between the 867 and 868, but your firmware is a newer revision than mine (HA13).

I have not heard of any C2 related issues on drives supplied by Apple, but it is possible. Are you able to test with any other drive?

If you set the log level to debug is there anything relevant in the log?

Sadly enough I myself can't test it at the moment as I am on a project and don't have any cd's with me. I'll try it out at the end of the week when I am back home.

" set the log level to debug "

Now where is that setting?

I should have mentioned that, sorry. You'll need to open terminal and issue the following:
defaults write org.sbooth.Rip logMessageLevel 2

It does appear that the drive is returning C2 error flags for quite a few sectors on the disc. Is this a new disc? If you clean it do you get the same results?

does this with any disk, no matter how good, new, cleaned or otherwise.

The rips I do get done without c2 are good! at least they sound better then any rips I did before (on a pretty high end system)(Also thanks to "play")
so there is nothing wrong with the ripping part, just the c2 flagging thing.

I will try to dig up my old LaCie firewire drive and hook it up to see what that does.

I just verified it with a brand new cd, straight from its packaging, and I do indeed have the same kind of log as PlayFan has, with the same behaviour. Seems to be a hardware problem then, no?

It seems like a distinct possibility- if you try the same disc on the same computer but a different drive and it works, then I would say the chances are 99% it is a hardware issue.

Same drive and same problem here. I'm getting 1000s of C2 errors and endless re-extracting.

Just reporting that with the same exact system, I have the same exact problem as the first poster.

Anything we can do about it?

Since this clearly seems to be a hardware issue, I was wondering if someone could give me a tip on a nice external drive that can handle C2 errors in Rip. It is probably a longshot as most people will use their internal drive, but I have to ask.

Anyone know if it might help to let Apple know about this (and where best to do this)? I've been searching on the Net a bit, but I can't find any reference to this problem except for here on this forum. I don't know exactly how iTunes does its rips, but apparently it does not use C2 error correction, because it would come across the same issue, am I right? Just want to figure out what my best option is.

Oh, by the way, can I assume that even without the C2 error check on, if the Accurate Rip check is correct, that my CD has been ripped correctly?

Cheers!

If the AccurateRip check is good, regardless of C2 setting you can be confident that you have a good rip.

I have three drives I've used for testing externally, but for ease of use I buy internal drives and then just hook up the MOLEX power cable along with a USB adapter so I can swap them quickly. I use a ByteCC USB 2.0 drive mate that can accept SATA, 3.5" and 2.5" interfaces and convert them to USB. I mention this specific product because I've tried some external enclosures where the bridge chipset they use doesn't support C2, but the ByteCC handles C2 correctly. Depending on what you want, your best bet may be to buy an external drive.

I have a Samsung SH-S202 and a Pioneer DVR-116, both of which I would recommend. I was sticking to ATAPI for these (for testing purposes) but I will get SATA in the future. There are probably newer models of each by now since they are over a year old.
