are able to return with the audio data. That is one reason why the program is slower than other exact audio copy windows 7 64-bit rippers. But by using this technique non-identical sectors are detected. If an error occurs (read or sync error), the program keeps on reading this sector, until eight of 16 retries are identical, exact audio copy portable but at maximum one, three or five times (according to the selected error recovery quality) these 16 retries are read. So, in the worst case, bad sectors are read up to 82 times! But this effort will help the program to obtain the best result by comparing all of the retries.

correct (at least that it can not be said at approx. 99.5%) the program will tell the user where the (possible) read error occurred. The program also tries to correct the jitter artefacts that occur on the first block of a track, so that each extraction should be exactly the same. On drives which have the "accurate stream" feature, this is guaranteed. Of course, this technology is a little bit more complex, especially with some CD drives which implements caching. When drives cache audio data, every sector read will be read from the drives cache and is that way always identical. Basically there are several ways to clear the cache. In newer versions it will overread sectors, so that the cache contains sectors from a position elsewhere on the CD. Advertisement / Anzeige EAC has several secure read modes, depending on the features of the drive. One really fast mode (nearly burst mode speed) is for drives with C2 error pointer support, accurate stream and are non-caching. Another mode (up to half of maximum speed) is for non-caching, accurate stream drives (without C2 support). If caching need to be defeat
Active Member Thread Starter Location: Edmonton Looking for help from any Exact Audio Copy experts! I've got EAC configured to rip CD's using Secure Mode with all settings correctly specified for the model of exact audio copy linux my optical drive. Track quality is normally 100%, but occasionally dips to the high 90's exact audio copy psp edition though never below 97%. There are no noticeable artifacts in the tracks I've listened to, although I've observed that with many CD's there

is a "Sync Error" which occurs at the end of ripping the final track; this in turn causes the error correction meter to go crazy. I'd say about half of the CD's I've ripped using Secure Mode http://www.exactaudiocopy.de/en/index.php/overview/basic-technology/extraction-technology/ EAC have experienced a Sync Error at the end, but never during any other part of the ripping process. I've listened to the rips of the final track from these discs and there doesn't seem to be any auditory glitches. Just curious if this is a problem, and if so, is there a workaround? I suspect this may have been discussed at the forums before but I can't bring anything up on search. FWIW the drive http://forums.stevehoffman.tv/threads/sync-errors-on-final-tracks-in-eac.179137/ is a newer Samsung DVD-R/RW DL external USB drive that EAC reports is capable of retrieving C2 information. Any guidance is appreciated. keoki82, Apr 1, 2009 #1 GreenDrazi Forum Resident Location: Atlanta, GA You shouldn’t have consistent errors at the end of your CD’s across a lot of discs. If so, I would suspect that this has been caused by bad handling of the discs by something like a multi-disc changer, a car CD player or some type of storage device. No easy way around it though. Clean the discs first. Try ripping on another drive to see if it handles the errors better. If you can’t hear any problems at these bad locations on normal playback, you could try ripping in burst mode.

Good advice. I've been ripping my entire CD/CD-R collection, and I've had this problem as well - but primarily on burned media that's more than several years old. Always the last track or so.

Up until recently, I probably found errors on only one disc, out of many ripped over the last couple of years. However, over the last couple of weeks, I have found read and sync errors on cds from three different sources. Though I could successfully rip some cds from the batches sent to me, some had a number of errors, listed as "suspicious positions". As many of you will know, some of these discs take a looooong time to rip. FWIW, I always clean the discs, when necessary.I started to suspect my pc dvd-rw, but after loading EAC and setting the offset correction on my laptop, I am having the same problems with the same discs. I loaded one of the ripped discs into Audition, but could not detect any audible (or visible) errors at the "suspicious positions". Given that many traders are concerned with "less than perfect" lineage, including rip errors, I was wondering what you think about this matter. Logged boojum Trade Count: (1) Needs to get out more...
