Disc burning gives verification errors in Finder and Toast

Several users have experienced an issue where various Macs suddenly stop burning disks (CDs or DVDs) with or without giving errors. In the Finder, users will get error code "0x8002006e unable to verify" after writing the contents of a burn folder. The burned disc is sometimes readable and appears to be intact, but every subsequent burn attempt gives a similar error. This issue has affected burning activities outside the Finder: Toast users appear to have the same problem.

"I'm having the same issue. Upgraded to OS 10.5.2 with my 20" Intel Core Duo iMac and I cannot burn discs. This is happening in the finder (burn folders) and with Toast 8 although Toast gives its own set of error codes."

Toast users will generally get an error stating: "Mismatch at byte 0/sector 0. Verification failed".

Fixes

Delete the Finder preferences file This disk verification error has been attributed to a corrupt Finder preferences file. Removing this file should clear the problem and resume normal disk verification. Open your ~/Library/Preferences/ folder, delete the com.apple.Finder.plist file, and then either restart the computer or logout and log back in (the Finder will recreate the file). When your user account has loaded up again, open Disk Utility and run a permissions verification/fix on the boot drive.

Reduce burn speeds If errors still occur, try reducing the burn speed to one or two settings below the maximum supported by your drive. This should lower the probability that a burn will fail, even if the software and preference files are functioning correctly.
