Recently I've bought the 2009 mono box set of The Beatles. When I started ripping the first disc of "Mono Masters", my CD drive slowed down and the estimated time of ripping "Love Me Do" shown in the program increased to several dozens of minutes. After several minutes, I stopped ripping, because I didn't want to wait for such a long time. I tried to rip some other albums from the box and I also had problems with some of them. I configured the ripping program such that it provides accurate results and that it uses error information from C2 pointers. When I changed its configuration to achieve fast ripping (which excluded using the C2 pointers) and checking results in the AccurateRip database, it showed that there are tracks that weren't ripped correctly, according to the AccurateRip database. Even after I turned on using the C2 pointers and waited until the tracks were ripped, there were AccurateRip mismatches on some of the CDs. I examined the surface of the discs that couldn't have been ripped correctly and I found some tiny signs - something that might be scratches or scuffs. They may or may not be the reason for the incorrect rips. These signs were not numerous. When I listen to the CDs in a CD player, the sound is normal, like the CDs weren't damaged. There are no skips and the sound is not distorted. I bought the box set on Amazon (it was sold directly from Amazon) and it was new and sealed so it is not a counterfeit. What are your experiences with ripping the CDs from the mono box set of The Beatles? Have you managed to rip all of the CDs correctly, fast and with AccurateRip indicating successful and accurate rips? I don't want damaged CDs and I would like to return the box set to Amazon and get another one, hopefully with undamaged discs. Do you think that Amazon will accept my return and complaint, taking into consideration that the box set is no longer sealed and the CDs can be successfully played in a CD player and you cannot hear any distortion when you listen to them when played? Have you ever returned a CD to Amazon, because it was damaged?
