Recovering damaged CDs or DVDs with Linux

On Windows there are a slew of file recovery tools which will peer intently at an optical disc, retrying until they recover every possible file. The leading tool is probably Isobuster, but there are dozens of candidates for the title. There are few automated (or even user-friendly) data recovery tools on Linux or UNIX(tm) platforms, but common tools which are often even included with the core system or which are installable through the official package system are often sufficient for performing this critical task.



One particularly frustrating way to lose data is by burning it to an optical disc and storing it. One often attempts to preserve data this way, only to have cheap media or a cheap storage container (especially binders) destroy the disc beyond repair. Sometimes, however, the data around the error (or at least up to it, which is sometimes still better than nothing) may still be readable if you use a tool more complicated than the 'cp' command (or selecting and dragging files in the file manager of your choice.)
