question about ripping rare cd's with errors
I'm having trouble ripping a couple of CDs in my collection and I could use some advice on the situation.

I'll use one CD as an example. It is by a local independant artist from years ago, so there is no way i can download it or get a new copy. The CD rips fine other than the first track which has errors and wont rip in secure mode(well the fourth track has trouble too because the test and copy CRC wont match, but the track rips fine at about 99.8% track quality with no errors). The first track plays fine and there are no scratches, so i can only assume that it is just a low quality CD due to the group being independant or the static and silence introduction to the song is confusing EAC into thinking there are errors.  As far as i can tell, I have two options for adding this CD to my archive, I can either turn off the option that stops a rip if there are errors and just rip it in secure mode or I can rip it in burst mode: I am wondering which of these 2 options would give me the better rip. Obviously this situation is not ideal, but indie is indie.

Thankyou for your time.

In that situation I would record from the S/PDIF out of the CD player into the S/PDIF input of my soundcard. Would it provide a bit for bit match with the original? I would have no interest in that question, only in how the recorded track sounds. Obviously you have no way to answer the question anyway, with this particular CD.

If stuck without  S/PDIF capabilities, I would record from the analogue out of CD player to analogue in of soundcard. There is a potential problem here, in my experience, in that many CD tracks will overload soundcard inputs, clipping. This means some attenuation may be necessary between CD player and soundcard.

A third option is re-polishing the CD bottom surface. Scratches and scuffing can prevent good extraction, but if that isn't the problem with your CD, the effort isn't likely to be useful.

I would first do both & listen to the results. If one has fewer audible glitches then your choice is obvious. If they both sound the same then you're in to technicalities I've never bothered to spend time on, sorry.

isnt that what hydrogen audio is all about? the technicalities? 
I am just looking for an answer as to whether i should use 'burst mode' or 'secure mode' with the 'stop rip on sync or read errors' option turned off in order to get a better rip.

Try ripping with another drive and/or another ripper like dBpoweramp and foobar2000. If you get 2 rips with the same MD5, then that would be your best bet.

I think that what you are being told is that neither of these is a good choice and that there is no way to tell which will give the rip with the least problems. If you are determined to go this route then flip a coin.

Look seriously at the alternatives that were presented though, because there are some very good suggestions there.

Also try limiting the drivespeed to the lowest possible. Then try either Burst or Secure mode. I've had quite good success with this. Also try different drives is a good recommendation.
Can't wait for a HD-AAC encoder :P

Try copying the CD to another CD using Nero or similar - worth trying a few CD drives as they do seem to vary in their tendency to deal with certain discs.

What advantage would that have over ripping in burst mode?

Skybrowser,

You didn't mention the SOUND.  Can you HEAR the defects?

When I get an uncorrectable error, of course it "bothers me".  But if I can't hear it, I try to forget about it...  And in time I actually do forget...  I can't remember which CDs/tracks had inaudible ripping errors!

  As far as I can tell HA is all about the technicalities of SOUND!

P.S.
Of course, if we can get a bit-perfect copy we are assured of perfectly preserving the sound.

I've got a handful of audio CDs which are impossible to rip with EAC's secure mode. What I did since EAC detects my Sony Optiarc DVDRW drive as non-caching was to rip with CDex using Paranoia Full which has given me audible error-free rips after listening to the whole albums multiple times.

Some of the issues I've had with discs are because of the drive used, some drives just don't get along at all with some discs, can't detect the disc at all, and require a different drive be used to rip them. Most of my drive issues were with drives newer than 2007, my old 2003 Teac has no issues.

That is an excellent example of some of the difficulties with DAE and how to address them.

Andavari, in the case of discs that won't rip with EAC's secure mode, did you find that burst mode gave you audible problems?

Those discs that EAC has serious difficulties with, i.e.; secure mode reporting no errors there was no difference in burst mode since the discs would still freeze my system. In other words I couldn't use EAC at all on those discs, it's like the discs were incompatible. I find it interesting how CDex in Paranoia Full mode could rip those discs with no audible errors using the same drive. Perhaps a drive problem with EAC?

One disc in particular that I can remember off the top of my head is 'Little Caesar - 1990 - Little Caesar' would cause EAC to completely freeze which would also freeze Windows about halfway through ripping it requiring a bad shutdown of the machine to get unfrozen. This happened three times before I gave up using EAC to rip it and then properly putting a warning note on the CD not to rip with EAC.

Those problem discs are all old audio CDs though, so I know it has absolutely nothing to do with any copy-protection/copy-damage.

to answer your question DOUG, no you can't hear the defects. So i guess i will try other drives or other ripping programs. Don't you have to pay for DBPoweramp though? I've never tried that one or Foobar before, and it took me quite a while to learn how to configure EAC properly so i'm not really looking forward to looking up more walkthroughs for more programs.

It's up to you if you want to put additional effort and/or money into this...  Like I said, if you can't hear the defect you can ignore it.

There are three different versions[/u] of dBpoweramp, including a FREE version.

I believe all 3 versions use AccurateRip, so you can confirm a perfect rip.  But, you already know that you're not getting perfect rips, and the pay-versions have more ripping options.

So i tried using a different ripping program and i got some interesting results.

I used Cueripper in paranoid mode and it gave me all the tracks with a quality of 100% BUT the problem track.... being the first track on this specific album shows 2 suspicious positions in the log.

I'm not sure whether the positions are at 11 and 13 seconds or 11 and 13 milliseconds. But i listened through the first 15 seconds of the track a good 10 times and it seems audibly perfect. I will link the log and you guys can tell me what you think about the situation. Although cueripper does say 'track quality 100%' for that track.
