Recover data from CD/DVD

It's also possible to lose data from CD and other removable media like a digital camera's flash card or USB thumb drive. Thankfully there are solutions tailored for these forms of media that won't cost a penny to use.
If you've got a CD or DVD that you're suddenly unable to access, try cleaning the disc first with appropriate cleaning materials, such as that sold online by Lindy (click here). If this fails - or you run into trouble with a
CD-R or CD-RW that you've burned data to on more than one occasion using multiple sessions - then try IsoBuster, which you can download for free from here.
   IsoBuster isn't fully featured by default - to unlock all of its features you need to register for US$26. Don't worry, though, because most of its data recovery capabilities are available for free.
   After installation, run the program and click Free funct. only. Now insert the troublesome disc and wait for IsoBuster to detect it: it'll warn you that a disc with read errors takes some time to show up, so be patient. The annotated screenshot below reveals how the program works. When you come to try and extract items, try the basic Extract Objects or Extract {filename} options first; if this fails, try the others - for example, Extract as RAW data can be used in conjunction with image files to try and recover all or part of the image. You can also try using PC Inspector Smart Recovery for media files on CD and DVD too - it may tell you the media is too damaged for use in fast mode, but use its intensive mode and you may be luckier. See here for more on recovering image files.
   Some drives are better at reading certain discs than others, so be prepared to try IsoBuster on a variety of different machines or drives before giving up.
