Commandline for erasing DVD-RW discs

I was trying to erase my DVD-RW disk in Disk Utility, and every time it had finished erasing it (either in Quick or normal mode), the disk would mount again with the same data visible.

A bit of poking around on the commandline revealed the optical disk cousin of hdiutil, namely drutil. So from the commandline you can do

drutil erase full

to erase a DVD-RW disk (I’d guess it works for CD-RW discs too). You then have to wait of course for it to blank all of the disk of course, but at least it’s actually erased so you can then re-burn it.

You could of course try

drutil erase quick


Also supported are

drutil bulkerase full

or quick for erasing lots of disks.

  1. I’d like to use DRutil to erase a disk without ejecting it at end (keeping it in the drive instead). But I guess it’s not doable.
