The bottom lines should say: 'No errors occured'. So the picture above shows a perfect rip.

This is the only thing you need to care about in this window. Sure... but what if 'Peak level' or 'Track quality' are not 100%?  (see picture above). Well, those lines don't matter : In my example (see picture) Peak level is 100% but this is not important (it just indicates the loudness). Track quality is often 100%, but in this picture it is only 97.3%. This means the track was difficult to read (the reason can be a scratch on the CD), but EAC still succeeded to make a perfect copy :-) Press 'OK' or 'Create Log' (it doesn't matter, a Log is made automatically anyhow). BTW it will be stored with your album folder.

NOTE: there is one kind of error that EAC does not report (CRC mismatch) ! More info further in the guide...
