Olli’s post @ Clone Clinic about all this SD2-crap: “This “regeneration” feature seems to cause a lot of confusion, so I should clarify what it does. When reading a data sector in any “RAW” mode (2352 bytes/sector and up) you get 2048 bytes user data + “other stuff” like ECC/EDC (Error correction information). CDs tend to get “scratchy”, so the error correction is used to check and recreate the 2048 bytes user data. Since V2.x CloneCD has e ECC/EDC correction in Software (cool feature! I hope you are clever enough NOT to disable it in the FES settings), which could “repair” some errors on the disc. Now I hear you scream: “Hey, you are not making IDENTICAL copies!” Well, yes. But I make “better” copies, so who cares? If a sector has errors which CAN be corrected, they SHOULD be corrected BEFORE the copy is made. Otherwise errors on the original would be on the copy + the errors which may happen to be on the copy. CloneCD 3.1 goes one step further. If a sector passes the CRC check (User area checksum matches) the ECC/EDC is regenerated. Why? It might be possible, that an error happens to be in the error correction part of the sector and is therefore unnoticed. If later on the copy an error is added to the user area, the error correction might fail to repair the error because it might be corrupted, or the CD-ROM would need retries to read such a sector. With CloneCD 3.1 you get “fresh sectors” all the time, UNLESS the error is not correctable. If it isn’t, it will be written “as is”. Further, some CD-Roms like to deliver garbage in the ECC in certain situations. I hope you got the point. Regarding SD2: Maybe it “might” work better now. If it does, good for you. The change wasn’t made with SD2 in mind. The “regeneration” change gives an overall enhancement of the copy, so it “might” improve the ability of CloneCD to copy a certain title on certain equipment. There is no “in-built” BetaBlocker or anything similar. If there was, I wouldn’t be able to sell CloneCD in certain countries like the USA.” Hope this clarifies it all once and for all!
