CDs and DVDs become faulty with time. If you do use them regularly they tend to become scratches and it happens that sectors on the disk fail and can’t be read anymore. This happens usually in a very inappropriate moment. Before you trash the CD or DVD you could try to recover most of the data on it with a program like Iso Puzzle.
Iso Puzzle creates an iso image of the disc that you place in the drive. All good sectors, that are those that can be read without errors, are written correctly and flagged as good while bad sectors will be flagged as bad. There is a reason for this, you can use different CD and DVD drives to read the media and add pieces of the CD or DVD that another drive could not read. That’s where the puzzle aspect comes into play, some drives have a better error correction than others and it could be that you can recover the full disc if you try enough drives.
Only the sectors that the previous drives could not read are tried again with the new drive. Just use the new drive as the source and the created flg file (where the good and bad sectors are defined) as the destination. New recovered sectors are written in an IMP file which has to be imported into the iso image after the process has finished.
If the CD or DVD is not recognized at all when you put it into the drive you have to click on Force Size and on Drive Reported in the window that pops up. Click on start afterwards to start the process.

Looks like a decent piece of software. I bet it depends on cdrom players too.
