The old hint Erase CD-Rs with an AppleScript gave me the idea to use Automator in 10.4 to make the process even easier...
I used the Run Shell Script action in Automator to create an 'Erase CD-RW' plug-in for the Finder. Here are the very simple steps:
- Open Automator and add the Run Shell Script Action (from the Automator Library) to the workflow.
- Leave all of the defaults, but type hdiutil burn -erase in place of the default cat.
- Save the workflow as a plug-in for the Finder (File: Save As Plug-In) and name it something like "Erase CD-RW."
Semi-obvious warning: This will erase the contents of your CD-RW without asking for confirmation!
