I would like to know how to create 1:1 “bit perfect” back-up copies (and/or images) of my CD collection. I have searched the net and the cdfreaks forums extensively, but unfortunately I feel like I have more questions now than when I first got the notion to back up my collection. I have a suspicion this isn’t the first time these questions have been asked, so my thanks in advance for the help - even links to relevant posts or articles would be much appreciated.
I am somewhat of a perfectionist, and I would like the back up copies I create to be 1:1 perfect copies of the source information. The posts I read mentioned that the optical drive itself can determine whether or not a true 1:1 copy is possible, with factors like “overread” and “sample offset” coming into play. Can someone explain what those two terms mean, and what specifications I should be making sure my drive has in order to make 1:1 copies?
I am somewhat concerned about error correction, as many of my CDs have scratches. I used Nero DiscSpeed to conduct a surface scan of my problem CDs, and I was disappointed to see many yellow sectors (damaged but still readable). Can someone tell me if the “damaged but still readable” sectors of my CDs will prevent 1:1 backups (due to error correction or otherwise)?
What is the best software & settings to create 1:1 copies? If someone could walk me through the process I would be very appreciative.
Is there a way to compare the information in a disc image (or a copied disc) to the original once a rip is complete?
Thank you very much.
PS - This is my first post, hello world!
