CDs can't be formatted unless they are RW(rewritable)..If you have a RW CD and a Cd writer, then you can use any software (Nero...etc) to erase all data on it ... proud_t@yahoo.com
You cannot change the data format once it has been written to the CD. You will need to write another CD with the data in music format to play in a CD player.
Windows 98 comes with no tools to format a CD, but there are several free programs that can be used. You can find them in the Related links section below.
