CDCheck is an application (or website) that allows users to check the integrity of their CD or DVD discs. It can detect and repair errors and defects that may have occurred during burning, copying, extraction, or reading of data. In addition, it can detect and repair problems with disc sectors that may have been caused by physical damage or aging. CDCheck can also compare two discs and show the differences between them in a graphical format. It also provides detailed information about each disc, such as the type of disc, its size, used and free space, and the number of files. CDCheck also offers a virus scan feature to detect potential malware. Finally, CDCheck can be used to generate reports that can be used for archiving.
