Try these tips:
- Specify a burn speed that is less than the maximum speed rating for the optical drive.
- Quit open applications you are not using. Open applications are marked with a white circle in the Dock in Leopard and with a triangle in Tiger and earlier versions of Mac OS X.
- Once a burn session has started, do not move, bump, or vibrate the computer.
- Do not put labels on blank discs before burning them.
- Use blank discs that are rated for the burn speeds of your drive, or consider using a different brand of media.
- See "Factors that affect writing to or reading from optical media".
Your computer may also benefit from installing additional memory (RAM) or a higher-bandwidth system interface for a burning device (such as SCSI).
You might also consider having the optical media device tested by an Apple Authorized Service Provider.
The Console utility or log may report:
Low disk space or RAM availability issues can lead to this. These are some clues that this might be the case:<
- The issue more often occurs during the burn process.
- The failed burn more often leaves data partially written to the disc, and the disc can't be reused.
Physical source of these issues can lead to burn failures and can sometimes be identified when:
- The issue more often occurs at the start of the burn process.
- The failed burn session more often leaves the media untouched and ready to be burned (it is still blank).
- The burn starts, but an external incident interrupts the session.
