When you insert a blank disc, your CDs & DVDs preference setting will determine what happens next. If it is set to Ignore, then nothing happens in the Finder. Follow these steps to change the setting:
- From the Apple menu, choose System Preferences.
- From the View menu, choose CDs & DVDs.
- From the "When you insert a blank CD" and "When you insert a blank DVD" pop-up menus, choose any action other than Ignore, such as "Open Finder".
- Quit System Preferences.
The next time you insert a disc, it should appear as expected.
Note: Applications such as iTunes, iDVD, and Disk Utility, can still access the disc even if it doesn't appear on the desktop or in the Finder.
