Formatting a CD deletes the data on the disc, rewrites the partition table and enables you to choose which file system you would like the disc to use. When the disc writes the partition table, it divides the disk into specific sectors so the disc can save data. ISO 9660 is the most popular disc format. ISO 9660 is mainly used for CDs and the UDF format is used for DVDs. Sometimes you can format a CD without first copying data or saving. To recover your CD, use one of several CD recovery programs.
