EAC: "Drive cache audio data" option question.
Reply #8 – 2005-10-17 12:56:18
To elaborate, if your drive caches, it will 'read forward' a larger amount of data when requested to read certain data from the CD, then read from this buffer until new data is needed. For EAC this is bad as erroneous data could be missed because of being re-read from the cache. So EAC's option is a workaround this problem and should be checked, thus causing the data to always be re-read from the CD itself and not the cache. [a href="index.php?act=findpost&pid=335019"][{POST_SNAPBACK}][/a] One more thing: What about the combination of the "drive caches audio" and "~drive is capable of reporting C2 errors" boxes? Isn't it unnecessary to check the 1st when you have the 2nd checked? Because when you rely on the C2 error pointer of the drive, EAC does not read the sectors twice anyway, so no need to "flush" the cache as long as no C2 errors are reported. Wouldn't it make sense to flush the cache only during the repeated readings that occur when the drive actually reports a C2 error? Otherwise the "drive caches audio" option unnecessary slows down the ripping process. Or am I missing something? Of course I know that not all drives are flawless in reporting C2 errors, but if you have a drive that is known to be reliable and you decide to rely on it, the "drive caches audio" option seems a bit weird to be activated also if no errors are reported by the drive.
