and it looks like some of them have food stains...
on the encoded side...
Of course, you can clean the bottom side. I've got a gizmo the polishes-out scratches, but I don't think it has ever helped when simple cleaning didn't work.
In case you don't already know, the data is on the top/label side, and the CD is read through the entire thickness of the polycarbonate.*
I'm sure someone else can help with the EAC settings. I'm not and expert on EAC, but when I can't read without getting reported-errors, I try another computer/drive. If all else fails, I just listen for the error and if I can't hear I try to forget about it! (That's assuming I can read the file well-enough to get a WAV file.) If I get an audible error there a few things I might do, depending on how important that particular song is to me: - Buy another new or used CD. - Purchase the MP3. - Try to repair the sound with an audio editor or noise reduction software. "Ticks" can often be removed with vinyl "click" and "pop" reduction software. If you have a skip or a stutter, there's usually not much you can do. - Try an "analog rip". (Often, the error-hiding features in the player will mask the error.) - Delete that file/song. (Although, I hate to have an album with a missing song.)
EAC will do some autorepair of WAV files but not MP3s.
Do you have any suggested/preferred software?
Hmm...an analog rip? I wonder if EAC's even capable of that, but it's worth investigating.
I don't believe that's the same thing as Burst Mode, at any rate - I think Burst Mode just ignores errors.
Finally, deleting that file/song isn't viable for me, unless I have a suitable replacement copy from another source (i.e. a compilation or "greatest hits" album). Still, some of these are so badly damaged that large segments of the data appaer to be unrecoverable, and EAC records silence.
In my case, I had a badly scratched CD-R that caused skipping on various parts of the disc, no matter how I ripped it in EAC. I ended up trying my standalone DVD player (and in this case, I was able to record its S/PDIF output, so it was still an all-digital capture), and the disc played completely glitch-free (although I'm sure there was quite a bit of sample interpolation going on in the player - sounded just fine, though).
A related question - what types of "resurfacing" or related devices have any of you used to attempt repairs to badly damaged CDs? I'm not interested in investing tons of money into this, but if there's a decent, reasonably priced option, I'll look into it.

When you're dealing with badly damaged CDs, will you usually get a better (more accurate) copy in "High" error mode - causing EAC to reread the same sector up to 80 times - or in Burst Mode, or in some other mode? Does the answer depend on how badly damaged that particular track is, i.e. how many sectors can't be read, or on the "quality" rating (83.3%-100%) given by EAC in "High" error mode?
That’s what the percentage describes: how many of the attempts obtained the same (most common) set of samples.
It is the ratio between the number of minimum reads needed to perform the extraction and the number of reads that were actually performed. 100% will only occur when the CD was extracted without any rereads on errors.
ONLY when there are suspicious positions reported, there are really uncorrectable read errors in the resulting audio file.
There is no software that will work the magic you request.
(I know many will question my ripping of each disc twice - once per format. But I haven't found any other way to preserve all of the metadata, including album covers, that I've painstakingly entered by hand. It's lost in my FLAC to MP3 processing, but there's probably something simple I'm missing.)
I agree that running EAC for too long on a badly damaged disc can be cause for concern. Right now, I'm trying to rip a single 7:30 track, and EAC is going on 24 hours for that one track. The drive's cooling down 20 minutes for every 80 of reading, but still...
chances are that there are lots of recoverables too
So as long as AccurateRip returns good results on the FLAC I'm not too overly concerned that the MP3 was faulty.
Don't kid yourself, we are neck-deep in irrational OCD on this one.
