It is without question that burst mode alone is unwise. However, it makes sense to me that if the test and copy CRCs are a match, than the rip is as accurate as it can get. In fact, I believe I have read somewhere that the author of EAC (Andre Wiethoff) uses this method all the time. In my mind, matching CRCs are a better way to gauge the accuracy of a rip than a mere message saying "no errors occured." I do somewhat question using this method on discs in less than fair condition. I do know that it is possible that a read error will give the same value twice in a row (but even secure mode would be compromised in that situation). I would be perfectly comfortable using this method as well if it were not for the opinions of those that firmly belief secure mode is the ONLY way to go. I would not be opposed to using secure mode, except I am re-ripping my CD collection into a lossless format. (I am kicking myself because I used lossy the first time). I do not want to spend an entire year doing this (I have over 1,000 CDs). Is there a definitive answer?

Matching CRCs does not mean a rip was accurate. Precise, yes, accurate no. I would dispute that. The track would be accurate. I would say it's near IMPOSSIBLE at such high rip speeds to get the SAME CRC if there was ANY errors on the disc. For all intents and purposes Bust Mode T & C with Matching CRC's is ACCURATE!

I'm guessing you've never encountered a consistent error before? I've seen plenty. The great thing about consistent errors is that you can easily reproduce your findings. Would you like to see some log files or links demonstrating this? No need to answer, here's one of the more troubling rips I've seen: CODE EAC extraction logfile from 9.
