But what if you accidentally scratch the disc at a later date and want to check that all the files are still readable? A disk checking program is an essential tool that you can use to scan CDs, DVDs, hard disks — in fact, most types of storage media. Disk-scanning utilities are also useful for checking that existing disks are still readable.

Emsa DiskCheck for Windows is another media-checking utility that you can use for CDs, DVDs, and other types of media.

An interesting feature of Emsa DiskCheck is being able to see other statistics about the CD or DVD you're working on.

You can also measure your drive's ability to read the disc by looking at the speed statistics.

This feature-rich application can scan for errors in a number of ways. It can check the contents of CDs, DVDs, hard drives and other types of media for errors and can also create/read hash files (MD5, CRC-32, etc.). CDCheck can also be used for comparing folders and files, which is a useful feature if you want to compare the files written to disc with the source files (normally stored on your hard drive). CDCheck can also double as a file recovery tool to recover files from a disk that Windows can't read. Overall, a great utility to install to keep a check on all your media.

Install Brasero from your package manager on nearly all Linux distributions.
