CD Check

CD-Check can be used to check the readability of the disc contents by performing byte to byte checksum. The software is available for free. CD-Check is a utility for prevention, detection and recovery of damaged files with an emphasis on error detection. It uses CRC and binary comparison algorithms. CD-Check can be used for all files visible by the operating system. This means everything that you can see in Windows Explorer (CDs, disk drives, floppy disks, ZIP drives) can be checked.
