Trying to format a CD or DVD? You can easily do so using your desktop or laptop! This wikiHow teaches you how to format a CD-RW or DVD-RW that is having problems playing or loading information using your Windows or Mac computer. You cannot format a CD-R or a DVD-R that has already been burned or otherwise written to. Note that formatting a CD will erase all files on it.

Formatting a CD-RW or DVD-RW

On Windows, open File Explorer, click This PC, select the disc, and click the Manage tab. Click Format, select your preferences, and then click Start.
On a Mac, open Finder, click the Go menu, then go to Utilities > Disk Utility. Select the disc, click Erase, and follow the on-screen instructions.

Insert the CD-RW or DVD-RW into your computer. The CD goes into your computer's CD tray with the label facing up.
- Most modern Macs don't come with CD drives attached, meaning you'll need to buy an external CD drive for your Mac.

Click Go. This menu item is on the left side of the menu bar, which is at the top of your Mac's screen. A drop-down menu will appear.
- If you don't see this menu item, click the desktop or open Finder to force it to appear.
It's at the bottom of the Go drop-down menu.
You'll find this app, which resembles a drive with a stethoscope on it, in the Utilities folder.
Click the disc's name in the "External" section that's on the left side of the Disk Utility window.
It's at the top of the Disk Utility window. Doing so will open the disc's properties window.

Click Completely. This option will allow you to completely erase and re-format the disc.
- You can also click Quickly here to erase the disc faster than the Completely option, though any errors you're encountering may not be resolved.

You can only erase a CD-RW, not a CD-R, so first make sure that is what you are working with. For the details you'll want to check out How to Erase a CD RW.

You can reformat a CD-RW as many times as you need, because the RW means re-writable.
