If you want to reuse a CD-RW disc, you must first erase the existing information on it. Before you erase the disk, make a copy of any files you don’t want to erase. Erasing, reformatting, or preparing a disk for burning permanently deletes all of the disk’s contents.
- Insert the disc.
- Open Disk Utility (Applications/Utilities).
- Click the Erase tab.
- Select the disc from the list of drives on the left. Make sure not to select the hard disk.
- Click Erase.
CD-RW discs may deteriorate after being erased many times. Check the specifications for the disc to find out its expected life.

Thank you for the help. However, when I go to the disc I want to erase, it doesn’t allow me to click the erase button. How do I erase the disc now?
If the button is grayed out, Saiyed, it usually means the disk is not rewritable. Does the disk actually say it is a CD-RW or DVD-RW (the RW stands for rewritable). If not, it can’t be erased and reused.
