    Losing confidence in CD Ripper

    Hello,

    A very interesting and quite vexing "bug-of-sorts" has come up with the most recent version of CD Ripper.

    I've noticed that when I accidently bumped the CD tray eject button when CD Ripper was ripping a single track, the CD ejected about 15 seconds later. The rip was in the FIRST PASS at about 30-percent.

    When the CD was ejected, the readout gave a green-i, secure, and a checksum... just as though it had read the entire track.

    Just to be sure, I checked the actual file and it was minimal, something like 50.2 KB. I deleted that file and tried a re-rip. I let it get 80-percent into the FIRST PASS again and this time, I intentionally hit the eject button. The exact same readout was displayed including the same CRC!!

    This is freaking DANGEROUS! 3/4 of my CDs are NOT in AccurateRip and most do not even have entries in Freedb or the others. As far as I can tell, the ONLY reassurance that I have that I have a good-and-exact rip is that the readout comes back with a green checkmark and "secure." All that means is that CD Ripper read all the mistakes exactly the same way twice. So, all of my rips could have multiple mistakes in them and I would never know until much later when the glitches begin to show.

    It seems to me that if the CD is not in AccurateRip you have absolutely NO clue and NO idea and NO assurance of the quality of the actual rip you are getting. Again, all a green check mark means is that ALL the mistakes were read the same way twice (or x-many times as per user setting).

    Many times, I will get a green-i (indicates that frames had to be re-ripped, possibly and undetected error has slipped through) and I have no way to check this out aside from listening to all these cuts/files in real time.

    Now, here's the BOGUS part. I had the CD tray ejected, so the CD was NOT in and was NOT capable of being read. Just as an experiment, I instructed CD Ripper to rip that one track again. And, it did! Not only that, it came back SECURE with a green checkmark and the SAME CRC. That is totally BOGUS!! And it is dangerous!

    Best wishes ALL,

    Love2fly

    This is a non-issue if you ask me, the CRC is the audio data passed out and it could be the 'block' that is passed out in such an instance so the 51KB file would not contain no audio samples, but a fraction of a second before the cancel event kicked in.

    Also if the Ripper had an inherent flaw you would see many posts on here because AccurateRip would find that flaw (for discs in the database).
