I decided to rip one of my CDs that has only been outside of its case once. I checked it carefully before putting it

into my drive, no dust, fingerprints, scratches, etc. I then ripped it with EAC, test and copy secure mode w/ accuraterip as well. (Maybe overkill, but now I guess not). After getting my report back from EAC, it stated no errors. Also the
How To Use Exact Audio Copy Flac
track in question even had its ripping quality in the log at 100%. I hit ok, the accuraterip window appears, and the last track was ripped incorrectly with a confidence of 12. Because mine is live CD, I thought maybe I bought different version with an extended last song, so I ignored this. I then went to check the CRC from my test. The faulty track was marked with a # I then extracted it again and the accuraterip as well as my own test exact audio copy not responding checked out perfectly. What does this mean? Most users don't bother doing a test in secure mode and an even smaller amount use accuraterip. Are such redundancies a bigger necessity for good rips than previously thought?I can supply options, a sample of the file, and anything else if requested. Also the CD is Led Zeppelin's How the West was Won, Disk 1, though I don't think it matters.

Andre has never claimed that secure mode is 100% secure... -Martin.

What are the chances of this happening? Is it an often occurance?

Eac Get Cd Information
recently trying to rip Metallica’s Load. I tried to fix the scratch at the end of the disc autoflac and ended up cracking it. I did manage to rip most of the tracks beforehand, but the last couple were giving me trouble because of the exact audio copy cover image scratch. I need to check to make sure that they are good but don’t know how to do it manually (obviously I can’t use EAC’s AccurateRip function anymore). I calculated the CRC of the WAV files but it does not match the ones in EAC’s https://hydrogenaud.io/index.php/topic,35168.0.html log file (either the one next to "Copy CRC" or the "Confidence" level). Does anyone know of a way to manually check a track against AccurateRip (and how EAC/AR calculate CRCs)? Alternately, can someone who has Load rip the last two tracks to WAV and calculate the CRC of the files so that I can compare them? Thanks a lot. __________________ -- Synetech 13-12-2007 #2 Prof. Honeydew CD Freaks Die Hard Join Date: Aug 2006 Location: The land of snow Posts: 1,336 Re: ?

Hi there, I can't answer that question specifically (and don't have Load - sorry )... but a couple of other suggestions may be to try listening to the ripped track and seeing if there any obvious problems. Also, try physically examining at the wave file as errors will probably show up in the wave that you can see. 13-12-2007 #3 DrageMester Retired Moderator Join Date: Oct 2004 Location: Honah Lee Posts: 20,880 Re: ? Need a WAV’s CRC (EAC-AccurateRip) The CRC of the last track can depend on the read-offset and whether the drive can read from lead-out, so the same disc ripped in different drives can result in different CRC for the last track. That being said, here's my (accurately ripped) result with Metallica - Load on a BenQ DW1655: __________________ Do not meddle in the affairs of dragons, for you are crunchy and taste good with ketchup. 13-12-2007 #4 Prof. Honeydew CD Freaks Die Hard Join Date: Aug 2006 Location: The land of snow Posts: 1,336 Re: ?

Some things I have noticed in my first attempts to use DBPA. I use a laptop with USB attached drives for ripping, exact audio I have several different drives (LiteOn, Optiarc, Plextor) all of which produce the same CRC values in EAC when used to rip discs (after setting the correct offset values for both read & write I am able to dulicate discs which are exact copies of the originals as the duplicates produce the same CRC values as well). I am currently using a LiteON USB drive (iHAS422 8 4L18) and have been using this for exact audio copy quite some time without issues under EAC. EAC reports it as having C2, no caching, a read offset of +6, and a write offset of -6. The C2 testing in EAC can be run to completion without issue and detects C2 error information properly. These numbers/features agree with those I’ve seen/found online. With DBPA the C2 detection seems to knock my DVD drive into some goofed up state where I need to power cycle it to get it working again and it doesn’t find any C2 information on the same discs which EAC finds it on. Also, I did a test rip of a CD and the first track showed the Rip Status as “Accurate (13)” which matched all the other tracks on the disc, but the CRC value was RED in color and according to the output shown at the rip completion, the CRC was different than what AccurateRip has for the CRC value of this track. How can it be verified as being Accurate when the CRC value is different? This makes me wonder if we can trust AccurateRip at all. I tried re-ripping that same track, and this time the CRC value showed in GREEN and I was asked to upload my result to AccurateRip which I did not do. Now on further tests with the s
open for further replies. stereoptic Anaglyphic GORT Staff Thread Starter Location: NY I've got two questions about EAC and I could not find anything over at the EAC forum (although I did not search all of the pages) Am I compromising the .wav file at all if I use the "Process wav" utility to fade-in or fade-out the first few seconds of a track? What does it mean when a number appears in the CRC column? thanks stereoptic, Oct 7, 2004 #1 Sckott Hand Tighten Only. Location: Hyannis Ma 1. Not really. It's a preference, and changing a wav that way isn't like going from PCM to another format and back again. The change is simple and in PCM construct. Do that if you prefer. It's no biggie. 2. CRC is called cyclical redundancy check. Explained: "A form of error checking in transmitting data. The sending packet includes a number produced by a mathematical calculation made at the transmission source. When the packet arrives at its destination, the calculation is redone. If the two figures are the same, this indicates that the data in the packet has remained stable. If the calculation at the destination differs from the calculation at the source, this indicates that the data has changed during the transmission. In that case, the CRC routine signals the source computer to retransmit the data. " So it's basically a footprint. If two people rip the same track from the same disc, the CRC should be the same (although I've never tried it). In duplicating CDs for personal use, this is ignored. Sckott, Oct 7, 2004 #2 stereoptic Anaglyphic GORT Staff Thread Starter Location: NY Thanks, Sckott. Regarding the CRC, just to verify, even if there is a "CRC" indication, am I still making an "exact audio copy", meaning that there wasn't any data correction? stereoptic, Oct 7, 2004 #3 SVL New Member Location: Kiev, Ukraine Sckott said: ... 2.
