If a CD ripper (that is used to copying of the majority) has a non-fixed bug, the same situation may happen too.Īlso, rare record or different optical disc version (pressing, mastering?) issues may be there. We can hope (without 100% warranty), that the majority (of similar checksums for some CD into the database) is the same checksum of the CD's original record.īut, in instance, if a serie of CD was manufactured without 100% identity to original studio files (for unknown to us reasons), then we have non-correct majority. So ripped checksum compared with an array of uncertified checksums. But the database doesn't contain original record checksum.
