I have a MacBook Pro Mid 2012 with built-in SuperDrive. MacBook Pro is running OS X 10.11. I am trying to erase a DVD-RW disc that is filled with some images. But the erase option is greyed out:

Greyed out erase button

Greyed out erase button 2

Note that I do can select a disk image and press Burn "Disk Image.dmg" to disc and erase the disc and write new things to it. But creating a disk image is very slow in my case and I would just like it to simply erase my rewritable DVD disc. Is there a way to use Disk Utility or a 3rd party app to erase my disc? Thanks.

Go into Finder and right click on the DVD, there should be an option "Erase rewritable disk". Apparently that's how to erase disks in El Capitan.


For anyone running High Sierra (10.13) or a similar version where a rewritable CD or DVD can't be erased from Finder because MacOS can't read it Disk read error

use the the terminal instead:

drutil -drive 1 erase full

See the manual for the full usage (man drutil) and ensure drive 1 is the particular drive you want if you have multiple.

This can happen, for example, if you have burned a live Linux image that must be bootable.
