CD-XRay, Explorer for CD-ROMs/DVD-ROMs

Summary: CD-XRay is a low-level explorer for exploring the innards of CD-DAs, CD-ROMs and DVD-ROMs. Everything you always wanted to know.


CD-XRay is an utility to browse the real contents of CD-DAs, CD-ROMs and DVD-ROMs. It can display the sectors in cooked mode (user data only) or in raw mode (headers, user data, error correction codes).
It offers classical navigation functions to display the real contents of data sectors.
