What is the difference between Formatting and Erasing a CD-RW?
Formatting a CD-RW typically refers to formatting the disc for UDF. Depending on your recorder and media (some come preformatted for UDF), you may or may not be asked to format when inserting a blank disc. If not, it happens automatically. Erasing a CD-RW returns the entire disc to its native crystalline phase, thus removing all data.
