The causes of an unreadable CD range from simple scratches to partially written sessions. A CD recovery utility is a must for everyone. My recommendation in this category is IsoBuster. It supports all CD / DVD formats and most file-systems. It can read old sessions, decode multiple image file formats, recover data from quick formatted DVDs and a hosts many other useful data recovery features.
It recovers files from a bad CD or DVD disc, saves important documents, pictures and video .This free utility will allow you extract anything on the CD/DVD to your hard drive.
Some use this feature to extract file from copy protected CD/DVD which is not legal.
