I have been getting this error whenever I try to burn a disc through Toast: I don't understand why, could it be due to how old the discs are possibly? After I receive that error, it shows up 4 more times, and then it says writing lead out, and now i can't use the discs anymore. I then try popping it back into the drive, and try to open it up in Finder, and it says i don't have permission for this task which makes absolutely no sense. I have tried making a DMG of the files I want to burn through Toast and that works, but I go into Disk Utility to burn it, and it says the disc isn't supported by my drive. Now I have been having issues with CDs as well, where when i burn a music disc through Toast and iTunes, random songs throughout the disc have static at higher frequencies in the song. So what could be the problem?
