I've been thinking about these ideas for a while, but not sure if these functions already exist or not. But most of these were geared towards DVD Decrypter, which was sadly discontinued. But here is what I have anyways. They might be possible or impossible to currently do, or never, but who knows. Here they are anyways:
1. More on the possible side of things is this. Let's say I have two copies of the same disc. If I know which sector is bad or not by comparing sector errors from one disc's log with another's, the one that shows up but doesn't in another's must mean it's a bad sector. Knowing that, maybe I can tell ImgBurn (DVD Decrypter...) to read it "x" amount of times for that particular sector. This is different than setting the number of retries under settings because originally, it will set the same number of retries for all the errors encountered (fake sectors or not). I want is to set a number of retries for a few or many particular sectors I know are not fake sectors, but ones that are bad because of dirt or scratches on a disc. This can significantly save a lot of time.
2. This might be impossible to do at the moment, but I'll share anyways. Let's say I have two discs that both have bad sectors. If I know which sectors are bad (but not fake) on one disc, but read perfectly on another genuine copy, maybe we can swap the bad ones with the ones that read correctly from the other disc. Then we can make a perfect copy from the two discs that both had bad sectors, but ones that do not have the same ones, otherwise a perfect copy cannot be made from the two.
3. This third one is sort of like the 2nd suggestion, but a little different. Let's say I'm trying to clone a disc, but I want to skip the first 2 million sectors because I know the first 2 million sectors of another disc are perfect. So placeholder sectors are slotted in for the skip ones (not sure if the term dummy sectors is correct here for the placeholder term I'm using) to save time. A cross comparison between the two BINS (or ISO...) are then combined with the bad sectors taken out to create a perfect copy from the two discs with different bad sectors than the other.
Is there a program out there that actually does the 2nd and 3rd suggestion? If not, can a new development project be built on top of what DVD Decrypter has already done as a whole separate project? There wouldn't be any affiliations to it as it is just swapping out bad sectors from one ISO with another ISO of another copy of the same source disc. Since this program doesn't do anything illegal as to decrypt or rip anything, it seems to be perfectly legal.
