If you use Disk Utility to verify CD-R or CD-RW discs burned in Mac OS X 10.2, it reports "problems" that it says need to be repaired.
Symptom
Disk Utility reports "problems" on a burned disc. You may see these messages:
This does not affect DVD discs or other applications.
Solution
The condition reflected in these messages does not affect the use of the disc. You may safely ignore the messages. You cannot repair a burned disc. To avoid the message on future discs, update to Mac OS X 10.2.1. For more information, see technical document 107036, "Mac OS X: About the Mac OS X 10.2.1 Update".
Note: If the same messages appear in Disk Utility for writable media, such as the computer's hard disk, you should allow the repair.
