I received several CDs from a friend that...have seen better days. (He just had them all loose in a satchel, and it looks like some of them have food stains on the encoded side...)
Anyway, I'm trying to extract what I can via EAC. I'm not at all concerned with how long the extraction takes; I only want to get the best (i.e. most accurate) copy possible.

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?

A lot of good suggestions, everyone. Thank you; please keep them coming.

I do use AccurateRip on EAC when ripping my FLAC copies; but I'm doing an MP3 rip first, and since I delete leading/trailing silence on my MP3s, AccurateRip isn't available there. So as long as AccurateRip returns good results on the FLAC I'm not too overly concerned that the MP3 was faulty.
(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 like the dbPowerAmp / CueTools suggestion. I've also thought about using Brasso, toothpaste, car wax, or that hard plastic filler that's used to even out scratches and pits in windshields etc. But I suspect the best solution would be to find a cheap professional resurfacing machine/service...anything that would be less than $1 per disc.

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...

One other thing I've found: updating my drive's firmware seemed to help a little.

Finally, greynol, I was aware of EAC's weakness in grabbing data from damaged tracks (its 8 out of 16 reads threshold), but I have no experience with dbPowerAmp, CueTools or any other CD ripping tool. Could you point me to a thread, or state your own opinion, on which software, in general, is most likely to result in the most accurate reading on a badly damaged CD? This is making two assumptions: (1) that a track passing the AccurateRip check can never be generated from the disc; and (2) that a certain piece of software will be superior on ALL drives. (And don't worry, I'll be searching the forums for answers too smile.gif )

There have been these discussions about foobar2000 losing album art in this conversion, but try the following with Mp3tag (freeware!):

- Create mp3s from your FLACs, using precisely the same folder/filenames. That ensures they are sorted the same way incoming.
- Dump the folder(s) containing the FLACs into mp3tag
- Ctrl-a Ctrl-c
- Dump the folder(s) containing the mp3's into mp3tag
- Ctrl-a Ctrl-v

24 hours for one track, that is more than even I have done. I've let a bad disc in overnight though. It wears the drive, but I have collected a few from end-of-life computers.


I disagree on the argument that secure will not improve over burst for a bad disc. You cannot recover the unrecoverable, but if you have a disc damaged to the point of one unrecoverable error, then chances are that there are lots of recoverables too. For a given disc and drive, only trial and error can tell.

Of course, but do you honestly think this will end up in an audibly better enough result to warrant the trouble? I do not.

If it's just a couple of minor spots that can't be extracted correctly then sure I'm all in favor of it, especially if CTDB can come to the rescue, but for a track that takes an hour or longer?!? Hell no!!!

Don't kid yourself, we are neck-deep in irrational OCD on this one. For those who really care about tiny pieces of good data in an otherwise hosed rip, your time is better spent looking for an alternate copy. If this is an extremely rare or one-of-a-kind recording, I do sympathize.

LOL! Truer words were never said.

pdq - I recognize that's a real possibility, but considering how badly damaged these discs are, I figure it's going to be impossible to reconstruct the original tracks. And to be honest, my hearing isn't good enough to hear random bad reads, unless they take the form of pops/skips.
