Here’s an option to recover data from unreadable CDs. (I haven’t tested this.) CD/DVD Diagnostic “works to retrieve a consumer’s damaged files corrupted by a defective drive, bad software or from user error”. It works on unreadable, scratched, or corrupt CD-R, CD-RW, DVD+R, and DVD+RW discs. Unlike programs that use Windows’ file system to access bad files, CD/DVD Diagnostic bypasses Windows and ignores the original software that created the lost data file. No attempt is made to repair the damaged disc. Rather, the unreadable files are repaired and written to your hard drive. It sounds intriguing. CD/DVD Diagnostic costs $70. CD Rx Data Retriever costs $40.
